Hi there, My question is, do (or can) hens splay their hackle feathers when they are "bumping chests" and establishing the pecking order? I'm not worried about their behaviour - I understand it's normal - but I have noticed that some of the birds will "bump", run at , or peck another bird but they never have the definite splaying of the hackle feathers while 3 others do. The difference is very obvious. On the white bird you can even see her black skin when she does this. Does this mean these 3 are cockerels/roosters? Thanks in advance! S & K.
