Whatever the first three BYCers suggest. I'm chicken illness and injury ignorant. No first hand experience, ty, with all but a few minor concerns which the birds largely resolved on their own
I got nothing - more often than not, I can't see the inside of mine well, and rarely candle this early. So Imma plead ignorance. Also, I usually candle from the bottom, not the side. Unsure if that makes a difference?
