I need opinions!! I have 3 rhode island reds approx. 7 weeks old. Two of them have bigger, redder combs and are taller. The other one has a much smaller more yellowish comb and is shorter and a little bigger in the breast. I got all three at the same time and they are all for sure the same age. I think that I have two roos and one hen. What do ya think? #1 (I think roo) #2 (I think roo as well) #3 (the one on the right I think is the hen) Thanks in advance!
