I am still waiting for my approx 26 wk old flock to lay. I noticed the hens' faces starting to get red and I thought that meant we were there. But now the ones I thought were turning red seem pale again. Could they have worms, making them pale? Would this keep them from laying? Also one of them has goopy runny poo, most of them have normal bird looking poo. The runny one has been that way her whole life.
