Hello, I have a question about when to put my birds out side in the coop. I have 6 chicks that are 6 weeks old as of today, and I'd like to have them out of my house soon. I think they would be much happier with all of the room they could have outside in the coop than in their cardboard brooder, but I worry that they will get too cold. I live in Montana, and we are still having a few nights that dip just below the frezing mark. I have one bird who hasn't quite feathered out on his back yet, and I worry that he especially will get too cold. Does anyone in a similar climate have any suggestions? My coop is a reclaimed old out building from 1940 that is about 10 x 20 feet with a 15 foot roof. There is no electricity in it. Thanks!
