Crowing
He is losing more color in his comb today. From when I have read that is consistent with how frostbite progress. Less red color means the blood flow is poor. It’s drizzling rain here so I didn’t bother chasing him for a close up. But I got a good enough one as he walked past.Seems to me that any airflow coming in the window would be suctioned up into the airflow going across the top up and over the roost.
What is the distance from their roost to the bottom of the vents up top? Your looking for a minimum of 12", I push more closer to 16"+. You could add a furnace filter to your venting, that would cut down on any wind coming in, but still allow your airflow.
Like said it does look mild if it is frostbite. I've got pics of Kong before and after frostbite, he looks better now than he did before
But his comb was huge.
The bottom of the ventilation is 13 inches above the roost bars. I honestly didn’t plan it that way. When I built the coop I was trying to use up as much material I had left over from my shed build and make the best use of anything I had to buy.
The roost bars could probably be lowered a couple inches but I would have to make some sort of brackets to hold them in place and still be removed for cleaning. The open window is directly in line with the roost bars so I think I’ll keep it closed anytime it’s below freezing outside.
I did add a piece of osb that I had left over from a previous project to break the wind coming in one side of the coop. It is a foot away from the vent so I don’t think it will impede ventilation just slow down the wind as it goes through
Btw the heat lamps in the pictures are fitted with nightlight bulbs not heat bulbs and are no longer in use. The birds were having trouble finding the roost before the sun went down when they were young. I have never bothered removing them after they got things figured out.
