Hi Everyone, I was wondering about what I should do this winter for my girls. I do not have an enclosed "coop" they are actually in a 10' x 10' modified dog run with a dogloo and a dog crate in them (with plenty of perches and even an area to hide under the crate). My mom has had chickens for years and thinks they will be fine for the winter in this since I live in southern california and it almost never drops below 35 in my area (and that is pretty rare). Right now my only adults are buff orpingtons and my younger birds who are still living in the house are 1 barred rock, 3 cochins, 1 americauna, and 1 silver laced wyandotte. Will my girls be warm enough? I also have one side of the run up against a solid vinyl fence and the back in the winter will be completely covered with a tarp. Any suggestions? I have noticed that my bo's will go into the dogloo when it is cold since there is no breeze and the only opening is in the front facing away from the wind. Any help would be appreciated. Thanks.
