Help! We got a mix of chickens at 2 weeks old, and now I think one might be a rooster. They're about 10 weeks old now. I'm concerned about the wyandotte (I THINK she/he's a wyandotte) with the red comb and wattles. Her feathers all still seem rounded at the tips, and she isn't starting any leg spurs yet. I HOPE she's a she! I've got a question about the light grey chicken, she's very slim bodied. Does anyone know what she is? And last, how about the dark brown one? Is she a Rhode Island Red? Many thanks in advance!
