Thanks for your advise. I'm a new "chicken mother" so I'm just worried about them. I did find that on the coldest days they tended to stay inside the enclosed area more do I guess they know what they're doing
It's 20 in NJ this morning. Dry cold. Thankfully not a lot of wind. But birds still want to be outside. So I let them. My polish just started laying again after a long vacation since Oct. So 3 eggs a day now.
