Lord N heaven I swear chickens will be the death of me. So my genius husband decided to put a rat trap near the coop (no poison) thankfully no chickens were caught in the trap but it did catch a rat. I Did not know there was a rat in the trap for 2 days. My chickens were feasting on its remains for two days (and so was the dog..awesome). One is losing all her feathers (3 chickens total). The other two seem just fine. This is my "alpha" female so I don't think she is a victim of pecking and her skin seems to be fine. They all seemed to go through a healthy molting at different times throughout July-end of September. Not to keen to think it is a Molt again. They are fed Lavena Plus and with an added vitamin mixed in their feed also chicken treats dried meals worms and food scraps. They are also free range. We never lock them up.Any words of chicken wisdom would be helpful! Thank you!
