Hi there! I have 6 of the little monsters and they are about 2 months old. I have seen them puff up a few times but because they are SO identical I can't tell if it's the same ones doing it or everybody. The only distinquishing feature is that 5 have the black tail feathers and one has the tail feathers that are the same colour as the rest of her (I say her cause she's the only one not getting a very red head the last few days)...would you say that I have only one lady? Or does that not mean anything? Sorry if this is an idiotic question...guess I could have tried googling the answer. My knowledge of turkeys is pretty much nil, these are my first and I really enjoy them - super funny. They're like puppies!
