    One of my girls ,three years old roughly, is consistently laying full size eggs with absolutely no shell, just the inner membrane.She lays these every few days and also has a very messy rear end.She has as much access to shell grit and recycled egg shells as the rest of the flock, who are all laying proper eggs and have clean rear ends.Any idea why this might be happening, please?

    I got this off of mypetchicken.com I hope it helps.

    Q: Why did my chicken lay a shell-less egg?


    A: Chickens need a lot of calcium to create good, hard shells, so most incidences of shell-less eggs in an adult hens are related to not having enough calcium in the diet. Young hens may lay a shell-less egg or two right as they begin to lay eggs for the first time, before their systems have "gotten into the groove" of laying. If your girls are on a proper diet of lay ration and have oyster shell free choice, they should have all the calcium they need. They also need Vitamin D and a proper balance of other vitamins so they can process the calcium. Lots of snacks or scraps can throw off the nutrient balance of their diets or give them too much salt.

    Disturbances at night while they are sleeping--a predator prowling around, or a big storm, for example-- can also sometimes upset their system and cause shell-less eggs. If that is what's happening, some of the other girls' eggs may have bands or "checks" on them, as the laying process was disturbed briefly before resuming its normal course. If disturbances are the problem, when they cease, the shell problems should cease, too.

    Another possibility has to do with the salt in their diet. Too much salinity can cause shell-less or thin-shelled eggs. So, sometimes if they are drinking water that is highly softened, it can contain a problem amount of salts for them.

    It could also simply be a defective shell gland; it that is the case there is nothing to be done about it.

    Lastly, infectious bronchitis can also cause thin shelled eggs, or eggs with no shells. Chances are good you would have noticed respiratory symptoms. If you suspect your chicken has a case of IB, you should get her to a vet for a diagnosis immediately. There are some other illnesses, such as egg drop syndrome, that could cause the same thing. If you have eliminated everything else, your vet may be able to help you.

    I go with what is already posted. She may be low enough on the pecking order that none is available for her

    Thanks for your posts.Milly should be able to get to the grit as they have plenty of room in their main pen of over 150 sq metres for 8 birds and are currently also free ranging in an adjoining larger fenced veg garden , so she can go back any time to feed or get grit.......and lay her eggs! Sometimes she lays on the dome roof and it's very tricky to gently rake them off as I can't reach them!!.I think she is low in the order but they have a good rooster and I don't see any bullying going on.Not many extra scarps , just the bugs etc they are currently finding, and more grass/weeds than when restricted to their main pen.None of the other chooks - Australian for chickens!! : - )) - are affected, all shells OK. One chook is sneezing but has been doing it for about three years and I have been told it's probably congenital as she's other wise OK.If Mill'y eggs don't come good I think she'll have to go to chooky heaven with Fifi , Beyonce , Liitle Miss Chatterbox and Mr Cloggs.........: - ((
