I'm the odd one out. I think your cock-a-doodle-doodler is the silver bird, dead center in the first picture, facing the camera. A lot of comb showing, IMO. But I could be wrong.
Thank you to everyone for your thoughts! We did find the culprit…our top hen, Tully! Their coops are side by side. When we went out early Sunday morning and realized it was coming from the other coop we were dumbfounded, lol! Opened the door and there she was crowing like she meant it. There’s a lot of drama going on with the babies in their sight. I read before it can happen. So there you go. Still on the fence with Dumplin’ though. Lol.
