I have a BSL pullet, BUT recently she seems to have be growing tail plumage and a larger comb. She is about 5-6 months of age and has not laid yet. She is definately top bird in the flock. She even rules my two roos (RIR & BR), she will grab them by the comb and swing them around in circles if they have the nerve to challenge her. They all give her wide berth. I have heard of chickens taking the place of the rooster and taking on the physical characteristics if none are around, but like I said, I have two. This is her running off the neighbors cat, like I said, she is a great guardian of the flock... She also has two little bumps on he legs like spurs are growing in. Any thoughts would be appreciated!
