I sure know how you feel! That is just what happened with my hen. Do try some of the remedies we've talked about in this thread, can't hurt, can only help and probably only big expense might be the vet -- I can certainly vouch for everything I've done so far with Lucy -- on top of the vet visits and a couple of injections (calcium and Lupron), I've been faithfully getting lots more calcium than what would generally be given into her, and as you can read above, it's certainly been working well, and problem has cleared up very quickly since a week ago. She was dropping "ugly" eggs for a month or two before I had the vet out -- wish I'd done it sooner because she was really not very well and losing calcium from bones and perhaps other body organs by time vet got here. I've always had the normal, recommended calcium around in food, feed, extra oyster shell, daily cheese, yogurt, etc. but it didn't fill the bill, at least for Lucy. And as I just mentioned just above, being flooded with all this extra calcium has benefited the other girls too! Please let us know if you try the extra calcium and things like calcium glubionate (which you can get from your vet or as Kay has found on the Internet) AND let us know how it works. Good luck with your girls!
