I have a sweet little white cochin hen i bought at auction last summer. Her and her identical sister. Faith and Hope. I spoke with the owner then and was told they both laid cute little brown eggs. Fine. Got em home,no eggs. ok Fine. Time goes by and I realize now neither hen was old enough to lay as they hadn't even started to grow a comb yet. Duh.So toward end of summer Faith starts laying evenutally as does sister Hope with no problems. Soon as frost started coming on came problems. At first Faith started about once a week doing the symptoms, standing like a zombie,wings out, not eating or drinking. First time I freaked but brought her in and put on a warming pad. About twenty minutes later she passed what looked like a balloon with a yolk attached. I kept her inside for a couple of days to make sure she was ok and then thought no moreabout it. Cut to now, she is doing this regularly about once a week and when she does manage to lay a regular egg, it sometimes is misshapen long and tubelike or with a wrinkle in the shell (thought it was a crack at first) Every time she does this I put her on a warming pad on my lap till it comes out and fill her up on water and she returns to normal as soon as it passes. Now today her sister is doing it too. I heard they might lack calcium? How do I give this to them, and why is it only in cold weather they are affected? I thought I usually catch Faithy every time, but two days back at dinner, she had the white balloon passed and the other hens were playing keep away with it, ugh. Now I have to watch for egg-eaters. I get that they are hatchery quality and this wasn't a problem maybe until now, as they are strictly pets. But they are pets that are very much loved and I dont know how to help them....Thank you for reading this and any help anyone can pass on to me. Sorry this pic wasnt part of it.... Hope and Faith as I bought them. Bald as an egg, no pun. The "thing" that Faith keeps passing The "thing" being shown off to husband, at breakfast no less. Faith getting bath after passing "thing"
