I got the rainbow egg layers assortment from MPC. The chicks came in on Wednesday, but I just got them today. My car is broke down yet again, so a friend picked them up for me. There are 3 chicks that have the white head spots, so my friend just assumed they were BR. They have dark on their legs as well. I was in there looking more closely at them (trying to figure out if I got ANY EE...doesn't look like it), and all 3 of the 'white head spot' chicks appear to have rosecombs? So these are most likely dominiques? Are there any other visual differences between the two at 1 week old?
