I know there are a lot of posts about introducing a new chicken to your flock but I have a question that I couldn't find an answer to. I have had a sick chicken recovering in a dog crate in my house for the past 3 weeks. She seems much better and I am looking to reintroduce her back to the flock. I have been putting the dog crate into the run where the other chicken are for the past two days and there has been a lot of interest in her. All the other chickens head into the coop for the night. Here is my question - should I bring the recovered chicken (in dog crate) back into the house or leave her outside? The run and coop are both secure so that is not the question - it is a matter of warmth. The chickens in the coop are of corse warm enough but will the lone chicken in the dog crate be warm enough. It is getting down to the 40s at night now and I don't want her getting more stresseed than she already is and getting sick again. Should I cover up the dog crate at night instead of bringing it in at night? I really want her to be accepted by the flock when she gets out ( she was the low hen in the pecking order before) and I don't want to her to get sick again. I don't have room to set up another run for her or room to put another hen in with her to help the reintroduction.
