Thanks so much for this very detailed explanation! It’s exactly what I was hoping for! Being new to this world AND excited to learn about it, these details will be helpful in my chicken future.I say Easter Egger because:
--pea comb, which is found on relatively few kinds of chickens. Comb types are easier to identify on adult chickens, but with practice you can usually learn to recognize it on chicks as well. A single comb sticks up and looks a bit like a comb you might use on your hair, with the tines pointing up. It is the most common kind of chicken comb. A pea comb is much lower and a bit wider, and often (but not always) has three rows of little bumps that look like peas (like the vegetable called peas.) Some chickens have a rose comb, which is even wider and flatter than a pea comb, and does not get tidy rows of bumps. There are a few other comb types, but those three are the most common.
--muffs (puffy feathers on the sides of the face.) Relatively few breeds have these, and to have both muffs and a pea comb means either Ameraucana or Easter Egger.
--color. Ameraucanas come in specific colors, while Easter Eggers can be any possible chicken color. This chick does not appear to be any of the colors that Ameraucanas can be, which means it's an Easter Egger.
--source. Pure Ameraucanas are fairly rare, and you typically will not find them in a bin at a store. Easter Eggers are quite common, so that's probably what you have.
So I think your chick is an Easter Egger. They are generally nice chickens: pretty, good tempered, good layers of pretty colored eggs, as healthy as any other kind of chicken. (Most will lay green eggs, a few will lay blue eggs, and a few will lay brown eggs.)
