I am a brand new chicken owner, we picked up 2 in may. My 8 week old white leghorn has made me question whether she was a roo or not from early on. "She" grew very fast and has always been the dominant one. The last couple of mornings when I open the run, she seems to be crowing??? Please let me know what you think, I had never heard of hens crowing, but after some research I guess that it is possible especially with the more dominant hens when no rooster is present. I attached a video of this morning.
