These are the last chicks of my order that I can't identify. One of them is the "free exotic" and the other should be one of my "assorted heavies". Possibilities for that one include dark cornish, partridge rock and sussex. ( those are the possible breeds that have striped chicks). They are both striped, but the bigger one has more feathering in. The chick in the first photo is significantly smaller than all the others. Not really shorter, but lighter.
