Interesting, they are both wyandottes. The chick 1-4 has a very large tail though, which isn’t a bad thing but it is interesting. She could be mixed with something to give her that large tail or it could be just a her thing.
The chick in photos 2-3 is a Blue laced red wyandotte, she has a very nice rose comb! Could you send photos of the other chick that you said was a wyandotte as well?
