Not sure if this is the site to post my question. But here it goes.
My coop is 8x10. I live in northern Ontario. I have 5 hens and will be adding more to maximize my space. I would like some one to tell me how many square ft of ventilation I need in my coop? Also, what iwould be the proper humidity reading in a coop that size considering all the weather elements this area can give ? Hope this makes sense.
