I have six baby chicks and I am a new time chicken mama so I would like to know what breed they are. Here are some pics:

There are a lot of possibilities at this age. If you can tell what type of comb they have that might help. I would guess welsummer for #1, buff orpington for #2. The last one could be an ameraucana/EE? I would take some closer pictures of those little combs, that might help!

At what age are you able to tell if it is a male or a female?
