Hi, we have what I hope are 4 welsumer ladies for their nice dark brown red eggs. They are just a couple days short of 8 weeks old. Two look very different from the other two - larger comb, tail feathers, feet, just over all a but bigger. Perhaps they are roos not hens or I have two differnt kinds of chickens. It seems that there would not be such noticeable difference in their growth at this point. Please look at the pics below and let me know what you think. Thank you Picture 1 - maybe a roo? Picture 2 - welsumer hen?
