My chickens are almost 2 years old and they have had no tails for at least a year and some of them have bald spots not just on the tail but even on the neck area. I have cameras on them so I watch for pecking but never see any and I’ve treated them for mites so I’m not sure what’s going on. I’m getting about 2 eggs a day from six chickens. Today I actually got 4 but that could just be from heat but I didn’t know if that had a role in what’s going on
