I was wondering about my chick. I have two of each: RIR, BO, and EE's. All suppose to be pullets. The smallest is a RIR that has only her wing feathers in plus one or two single 'big feathers' coming in. My babies will be 4 weeks old next Tuesday. I was wondering if I might have a roo on my hands.. She's the smallest one of the bunch and seems to rule the roost(or so she thinks). She always runs at the others and does the wing flap thing. The others are kinda short and fat, while she is taller and skinnier. She seems to have longer legs and stick her neck out a lot. What I call the 'hey whats that? whatcha looking at?' thing. Her combs is just like the others, pink and sorta small. I was just curious if this is roo behavior?
