OK here is the story one of my mamma chickens has decided to rejoin the flock leaving a lone 8 week old chick. Mamma and chick were kept in dog crate in the coop with the rest of the flock(one of the hens killed one chick so this was out of necessity. )My concern now is its supposed to be 20 degrees tonight and I'm worried if that will be to cold for the chick? I have put lots of straw in and around the crate but am still concerned. Just an FYI this is my first winter having chickens so any help or suggestions would be greatly appreciated.....also I'm located in Michigan so we have wind and snow right now
