| Soft eggs - main causes Old hen, ex-battery hen, nutritional problem, toxins, parasites (internal and external), illness, management problems, shock and Coccidiosis. Ok so here goes.... hen physiology and nutrition 101 (the condensed version - I mean condensed we did a whole year on hen anatomy and physiolgy at college and i'm doing it here in 1000 words or less!) lets start with calcium - a very likely culprit hens store calcium in the medullery bone, they store more than they need so by the time they are laying soft eggs calcium levels have been a problem for quite a while. A hen who eats a balanced formulated diet will NOT have a deficiency in calcium in the diet (assuming they are eating enough) - however calcium uptake and calcium deficiency are two totally differnt things! Increasing calcium in the diet is not necessarily increase the calcium in the bird. Phosphorus is a limiting factor in calcuim uptake, ie phosphorus stops calcium being abosorbed and vica versa, however phosphorus is vital in the diet and also aids in shell formulation - calcium and phosphorus are both consituants of bone. Vitamin D is the facilitator in calcuim uptake - if vitamin D is deficient then calcium will not be taken up by the bird regardless of how much you give it. Vitamin D one of the best non meat based sources of Vitamin D is eggs!! Vitamin D deficiency can be caused by insufficient in the diet or a liver problem (its a fat soluble vitamin so is processed in the liver) To increase the calcium uptake in a hen quickly requires a small particle size that is quickly broken down - limestone flour is the best for this, but for this to be effective you also need to increase Vitamin d in the diet (for short periods poultry can tolerate 100 times their requirements for vitamin d so toxicosis will not occur) - best way is to buy preformulated vitamin drops designed for birds - any birds the budgie one will do, its the same stuff just differnt dosage. feed this in the diet for a week, if you want to make sure she eats it make it a treat in the afternoon mixed in wth some pasta or sweetcorn or anything she will scoff down. If soft eggs are still being laid after a week then its not calcium deficiency. If eggs are starting to return to normal then continue feeding this for another week and then cease feeding the extra ration - if eggs remain normal it was a blip (it happens 1001 causes) - if they return to being soft then there is an underlying problem - this will need investigating Toxins - the most common toxin your hen will ingest is a mycotoxin called aflatoxi, it is a produced by a mold found in corn, this is one of around 3000 mycotoxins that your bird can ingest, mycotoxins can interfere with the absorption and metabolism (use) of both calcium and Vitamin D amongst other things and this is the usual cause of deficiences when an otherwise seemingly appropriate diet is fed. Note on above - this is for a calcuim defficient bird - an excess of calcium will KILL your bird and I do not advocate feeding limestone flour or any calcium pills to an otherwise healthy bird on a regular basis, oyster grit can be offered in a seperate pot to the feed the hen will take only what they need and the particle size means that only small amounts of calcium enter the system anyway. excessive calcium will stop the absorption of phosphorus and some otehr vital trace elements and ulimatley cause death. Next parasites - internal and external will strain the system, internal will obviously utilise the nutritional benefits within the feed before the hen gets chance to do so - this gives you a nutritionally deficient bird!! Management problems (not accusing you just stating causes) - insufficient or innappropriate feed is given to the hen also insufficient water, without water a hen cannot absorb many of the nutrients in the feed and they are excreted without ever entering the hens system - not going to tell you the outcome of this as you are not stupid!!! Illness - again many illnesses can cause nutrition andphysical problems, liver problems, respiratory problesm, coccidiosis - all obvioulsy cause problems for then hen but I'm going to bypass this as you have not mentioned that she is otherwise ill. Are you all bored now and have nodded off - lots of information to take in, but all highly likely contenders in a soft egg layer. All of the above is only of any use if she is a soft egg layer who is then eating them because they are an easy target if she is an egg eater then it will be probably of no use what so ever. egg eating can be a deficiency in the diet, salt or vitamin d or protein are the main culprits, but it quickly turns into an unbreakable habit - then its Richmonds suggestion of doctoring an egg for her to eat

| Petal, I paid £12.01 inc of p&p for 60g Flubenvet from Animal Medicines . Received within two days of placing order and one day was an RM strike day in London.

| Thanks for the fact sheets BarlingPoultry, very good. Do ALL hens moult EVERY year? Two of ours are bats, and one of them is virtually bald Is this normal??

| Once they're about a year old they do and yes it is normal for them to go bald or oven-ready as some Grapes describe them The Hen Trust publish knitting and fleece pattern to make 'jumpers' for batts who are fresh off the farm to enable them to cope with the drop in temperature.Help us make hen jumpers!

| Hi everyone, Really glad you found the fact sheets helpful. As we said, we change and update them constantly as we find out new bits of info ![]() Our biggest surprise with people is the worming, people think to worm their dogs and cats but often have never wormed their hens. People say their hens are old and have just stopped laying. More often than not, we suggest worming, and these 'old' hens start laying again! We are busy rearing turkeys for Christmas at the moment, but from January we start selling chicks for people to raise as table birds at home - as people are much more aware of the conditions poultry are kept in these days. We usually have growers or POL all year round though.

| I think a lot of people don't think about what hens need, BP. I've lost count of the times people have said to me, "oh chickens are easy to keep, you don't need to do anything to them". So I think, but what about de-lousing, de-worming etc etc. These people are also the ones who turn round and ask "why are my hens not laying?" It's amazing how many people replace their chickens after a year or two saying they are not laying any more. It's usually because of healthcare issues that they are not laying, rather than they are old or spent. |
