Just got our first 6 chicks about 3 weeks ago. We got 2 RIR that the lady we bought them from accidently ordered as straight run. The first night home we were thinking that one of them was a roo just because of the way it was strutting around the box and standing up taller than all the others. It also feels heavier than the rest now and has a much bigger comb and wattles. Here's a pic of the one we think is a roo: And here's the other RIR for comparison: WDYT? Is the first one a roo, or is it too soon to tell? Also, when we bought the chicks they were all the same size, but our silver leghorn is now about half the size of the rest of them. Does this have something to do with her breed, or would there be some other reason for her small size? Thanks!
