Our local feed store ordered the rare breed assortment from murray mcmurray and we got 5 baby chicks. The only 2 breeds we are 100% sure on is our naked neck and golden polish. I have read for them to be a "easter egger" or the ither 100 different names people call them, they need to have the tufts. One doesn't but she has that chipmunk colorings. Also there was a chick which we didnt get that was a cooper colored one with the chipmunk markings. I looked through the catalogs and couldn't find a chick matching that color. Any thoughts? One last question. 2 of our chicks are about a week older than the 3 we got today.. when can I place dirt in the brooder? Do I need to sift it?
