Hmm that's tough. Some times hens appear to have saddle feathers put then when they get older it results in a big fluffy butt. And sometimes hens have a tail like that and it just turns out to be a curved tail on a hen. Tough.
Thanks chickenlittle21. Yes, but I have another chick almost identical and it is usually those 2 that exhibit this behavior. Probably just need to cool my jets and let nature take its course. I will know in a few weeks for sure. It just seems I am in the pasture with them so often I can't see the changes. Sort of like you don't notice your own children growing but others do! They are fun though!
