I had wondered about that, especially as we live right next to the delivery door for the town’s post office. Then, we had to bring in the younger/smaller cockerel and his crate-mate the other night, after doing a night check on everyone and finding the pair of them thoroughly soaked and his comb’s tips blue.That is the problem with multiple roosters. Once one starts it becomes competitive, especially in the dark as the submissive rooster is safe from any repercussions that the dominant rooster would normally dish out for crowing in his presence.
I don't know what your lay out is like but could it be a car's head lamps sweeping across the coop at that time, as it comes along the road, perhaps someone heading out to do an early shift on a regular basis.
We’d been having heavy rains all day, and the winds had slanted the rain sideways, spraying it into his side of the structure.
They spent the night inside a windowless area around the corner from my bedroom, and I can now inform everyone there’s NOTHING quite like having a fully fledged crow happen in the middle of your dead sleep, in a small area, where there’s bare walls and a cement floor.
I nearly punted my poor dog into the ceiling when I bolted awake shouting god-knows-what. LOL
So unless it’s something that becomes a set pattern once they’ve had a “false sunrise” instilled… I don’t know if it could be that.
But it does still make sense, considering the lighting & placement!
I’m going to see what we can do to alter the roost layout so the post’s lighting and movement aren’t so troubling for them.
