Girls are roosting outside just when it starts getting cold? Help!

That's nowhere near enough ventilation. General rule of thumb is you want 4sqft of coop space, 1ft of roost space, 1-3sqft of ventilation and 10sqft of run space per bird at a bare minimum. Less than that and you're more likely to run into problems

Thank you. I’m going to address the ventilation issue immediately and am in the process of building out the larger run. I’ll have to stick to the coop space for the time being. I hope that with better ventilation and the adequate run space, at least the birds habitat issues will be met. I’ve been fortunate this far that the birds have had enough free ranging each day to get the exercise they need.

I really appreciate the numbers. I math out the 1-3 sq feet of ventilation and get on that pronto.

Thank you.
