I'm grasping at straws here 'cuz I'm a chicken newby myself, but have you tried worming your birds? Also, you might want to send @chicken danz a PM. She has LOTs of experience and might be able to give you some other tips.Thanks Sharol,
The K-State guy said as a Brahma she wouldn't be laying yet. But at some point in this - it's been going on now for almost two months, one of the hens laid a perfectly round egg about the size of a quarter. I also found a bare yolk one morning. It may have come from her because, as I said, the others have alid beautiful eggs since the beginning. only a couple of gigantic double yolkers from the Leghorn.
Wish I was a chicken vet!
