We got a batch of straight run heavy breeds from McMurray a couple of weeks ago. According to McMurray, they are: Our choice of varieties, but we guarantee at least 5 different ones from this list: Black Australorps; Lt. Brahmas; Dark Cornish; Black and White Giants; Buff and White Orpingtons; New Hampshire, Rhode Island Reds, Barred, White, Columbian, Partridge, Buff Rocks; Sussex, Turkens; White, Silver Laced, & Columbian Wyandottes, Red Star and Black Star. This dual purpose assortment is sure to satisfy your need. We've definitely got five breeds, and I haven't really tried to ID any of them except for the partridge rocks. Pretty birds, nice and healthy except for a couple that died the first day. But...I'm wondering if we got some Cornish X by mistake. Four (or was it six?) of the chicks are giants, dwarfing all the others (which are already large breeds). The chicks are white, and appear to be growing so quickly the feathers can't keep up --- there are pink spots visible all over them when they're under the light. They've got the super-thick stumpy legs the Cornish crosses seem to have, too. The only chicks of the breeds they listed that start out white are White Rocks and White Orpingtons. Big breeds for sure, but that big? Here are a couple of pics. My apologies for the quality; I took the good camera, only to find the battery in the flash dead when I started snapping. As it's raining here, I didn't go back in for new ones. Anyone know what I've got? If they're not Cornish X, I want to get more next time we order!
