Earlier tonight I posted on the emergencies page that one of my BAs, 8 months old, was egg bound or had a broken egg inside. Thanks to the advice on BYC, I brought her into a steamy bathroom in a dog carrier. Within 30 min. she had passed an egg with a thick membrane instead of a shell. I checked her again a few min. later and she had layed another membrane/not shelled egg. Both eggs were a runny mess. I feed 20% layer feed, Super Breeder, and provide free choice oyster shell in the coop and in the run. She's been laying for 2 months and her eggs have always had beautiful hard shells. Last normal egg was last Saturday. What could be causing this and is it unusual?
