I have a Barred Rock hen 8 months old. She has not layed an egg yet. I have read previous comments about stress. Right now she is stress free, healthy, has a nice big coop plus a yard, good food, est. HOWEVER, we bought her as a baby with a red hen and that one died a horrible death by a hawk when they were 3 months old. THEN.. we got another red hen immediately and 2 months later that one died in front of the Barred Rock hen. Then...we got 2 more red hens for her and they appeared sick so I removed them from my property asap. Could all this be the reason my hen wont lay?? Shes stress free now but that's a lot for one hen to witness??
