Just for you who are concerned about cold chicks, this morning it is 21 degrees here. I went out to let out the chickens out of the coop and mama and the 6 chicks were in their nest. As I was cleaning up the night poop with it as cold as it was, mama got up with the chicks and went over to the feed and water. They stayed there about a minute or so. Ido have sand down instead of shaving and no cold seemed to be "transfered" as I read it does. I even put my hand in the sand and it just wasn't cold. Anyway, they all took a dump and mama went back in the nest and the little ones following her back in. So that tells me to keep the chicks at a certain temp all the time is not something mama does. They were certainly ready to crawl back under mama and she knew it was time. They all streached themselves themselves out good with that minute of running around. As soon as the sun comes out they will be over at the big glass door sunning themselves and takes their dust baths. Mother nature seems to really have a handle on what to do. And for this hen to not even be a year old yet, she is quite the mama. This post is just to try and ease some of your minds about cold chicks and bringing them inside for fear of them getting cold. Some acclimation is needed. To make them stronger adults. I think so anyway.
