Ok so I have a 10- 11 week buff orpington cockerels that I have been hearing strange noises coming out of. Its not his usual chirp chirp. It is more like the last part of a rooster crow. Kinda like DOOOO, but it doesn't last long, only like a second. Does anyone know why and what he is doing? Thanks in advance!

I brought him inside for a minute today, and I realized how huge he was. My little chick isn't a baby anymore lol. Thank you for all your help! Now I know that he will start being the alpha male sometime soon! I think I said it wrong earlier when I said ALPHA HEN lol I couldn't think of the right word at the moment.
