I do a sniff test each morning when I walk into the coop. I keep the pop door open all day. I've been keeping the East window open depending on the which way the window is blowing. Today I had the West one open 1/3 of the way all day. Tonight it's cracked. It's 20 out--37 in the coop.It is different.. I would use your nose. Close up the coop for a week and test by smell. If you smell your chickens or ammonia you need to crack one of the windows. Do you leave the coop pen during the day? Poop door?
Thank you again, Del!!
Your muskrat & my dogs!Came home this afternoon and a muskrat was up by the coop eating frozen FF...at least someone likes it.
