Hello! I am a total newbie at raising chickens! We recently let our hens into their run from the coop. I live in the Midwest and weather is literally bipolar. Yesterday was 75 degrees and today it’s snowing heavily and a cool 34 degrees. Anyways, the leader of the flock is sitting on top of the entry to the coop and calling urgently it seems to the other hens? She’s been doing this for quite a while. The others don’t seem to be in distress but I can’t help but think something is wrong? Are they too cold? I have their coop under a large tree sheltering from wind and snow. I have one starlight Easter Egger, and two brahmas. Thank you so much!
