i purchased 8 chics in October. The breeder said he was pretty sure they were all females by inspecting feather structure. Now at 5 months I am waking to the sound of Crowing at 5 am. Only started this week. I saw two crowing this morning.. but they all look alike. Only one chick in the flock has a small comb and waddle. All others are very similar in looks but looking at photos of hens and roosters they look very similar to rhode island red hens! How do u actually tell them apart? No eggs yet either.
