I was out feeding the goats and chickens this morning before I went to work and heard a doodle-doo coming from the coop. I thought "what in the world?" I heard a rooster crowing but that was from a nieghbor that lives down the street about a half mile. I didnt think nothing of it and continued to feed the goats when I heard it again....mmmmmdoodle-doo. I thought "no way!" I am supposed to have 5 hens. I got them as pullets, around 8 weeks old and one or two of them are growing out of their peeping stage. I am hoping that this is just a phase for the hens trying to stretch out their new vocal cords or do I have an unintended roo in the bunch? I have 4 Doms and 1 RIR (all supposed to be hens). How can you tell a Roo from a Hen at around 9 to 10 weeks of age? Any advice would be greatly appreciated.
