Polish that I recognized right away (pretty easy to spot) I also have some easter eggers and for the rest no clue really, we bought a package of mix breed hens online so it can be a bit of everything, and I am pretty bad at identifying chicks so I guess with some it will be a surprised which we don't mind.
That's fun! I considered doing that, but I really wanted a variety of egg colors so I picked them out instead. I stink at identifying them too. Does the one in the first picture have feathered legs?
