I have a few questions about molting. everypost I have read says are the pin feathers there what if they are there but mostly at level of shin, also do birds molt together for a reason. my sil told me the other day she tought the hens were getting picked at well it seems all my cochins the hens are just their necks so far and the roos the feathering on the back of their heads seem to be thinning out. I checked for lice but did not find any but spead out DE as it is time anyway. do birds normally do this together I also have a rir and 2 leghorns and they seem just fine. I would almost think mating as each roos favortie hen is looking bad but the backs of the roos heads? Not sure on age of 1 but other is actually a pullet about 8 to 9 months old. How long does this normally last I have 4 chickens that lay regularly 1 is broody and these cochins are 2 of the others and the other one lays regularly just every 3 days (she is a little older).
