This morning one of our hens didn't come out of the house when I let them out. She's been laying and had a bright red comb but this morning it's pale. When she did come out she was seen stood hunched with her tail down but is interested in food.
We lost our cock a few weeks back and his comb turned purple so I'm now worried something is linked? They haven't been wormed for a while could this be the cause? How often should they be wormed?
I'll check her crop in the morning when she comes out. Any ideas?
