2 roosters and 3 hen - 1 rooster is in hen house at night others are not

[RDCPF2599]

I have 2 rooster and 3 hens and live in western PA. It has been really cold at nights. I have a small red light in the coop. For the past week, one rooster stays in the hen house and the other 4 hang out and sleep on a perch outside the hen house in the coop. Our coop has polycarbonate roofing panels attached to wire on the coop walls to shield the chickens from the wind and snow. My son and I have been moving the 4 four outside to the hen house and closing them in at night since the temps have been freezing.
why are they not going into the hen house? could the red light be the problem?

Could it be that one of the cockerels has “claimed” the hens and doesn’t want to take them around the other? There’s one too many cockerels for your hens...

The light and heat from the light may be uncomfortable. Most chickens require no extra heat. I would remove it and see if it changes.

Otherwise you have too many roosters, that may be the problem, and it may not.
