Hello, I just got four Easter egger chicks this weekend they are all supposed to be female. I am concerned that one in particular is male. one of them is 2-3 weeks old and the other three are around 4 weeks old. Lets refer to them (from left to right) as red, yellow, black, and brown. Brown is the youngest. Side view of yellows face. Red's wings Black, the one to the far left is the one I fear may be a roo. It's wing feathers are shorter than the onther three and it is one of the older ones. Brown, the one to the far right is the youngest and has just as long or longer wing feathers than the older ones. Thank you in advance for your help.
