Our chickens are 15 weeks old, 6 are Rhode Island Reds, unsure what the lighter brown are supposed to be. They all should be female but obviously they're not. A couple of (the RI reds) them are crowing, help us figure out what they are.

I agree. Every dark one (RIR) is a cockerel, while all the light ones (New Hampshire Reds) are pullets
