I'm not going to post pics of these chicks, but I just have a question in general about different breeds. I just got 26 rainbow layers from McMurray on Monday, and am eagerly trying to guess breeds of birds. I have 3 little buff babies, and I am curious as to the differences in appearance between buff orpingtons and buff rocks. Is there an obvious way to tell the difference between the two? I'm sure when they're newly hatched, it is difficult, but as I watch them grow I'd like to know what to watch for in identifying their breeds. I know there are other buff varieties of birds, but these two have me stumped. I have 4 little white babies. Same question as above. I can tell a leghorn, we've had enough of those and they are obviously very different than the larger bodied white birds. What characteristics set white rocks, white orpingtons and white giants apart?
