My 4 hens had not been laying for at least a month and a half. They seem healthy, they have normal poop and they act normal. They are not molting or hiding their eggs and they are eating the same chicken food they have been since July. The only thing that happened before we stopped laying eggs is the rooster found a new home, and he was not really nice to his girls. Do you think it is a worm infestation? I don't care about the lack of eggs...... (well it would be nice to have some eggs ), but their health.
