My chicken coop is almost done, should be finished by tomorrow. The brooder is getting small as my chicks are getting big! I have 18 that are about 4.5 weeks and 7 chicks that are about 1.5 weeks. They do well together in the brooder but I don't want them to start getting irritated with lack of space. One problem is that my run is not complete yet. It will probably take another 2 weeks to finish. The coop is big; about 12'x8'. I know it is way too early to bring the 1 week chicks out to the coop, and possibly too soon for the 4 week ones, but what if I bring the brooder out there and let the older ones go in and out of the brooder whenever they want while staying inside the coop? Several of the older ones have already made escape attempts. I wonder if this would help avoid a total separation because otherwise I would have to re-introduce them again in a few weeks and I want to avoid that. Any thoughts on this, or other suggestions? And as for the run, is it ok that I put them in the coop and just keep them locked in there until the run is finished? What if a few of them escape when I come to feed and water? Will they stay in the vicinity as a safe zone? How do I make sure they come back? I am nervous about free-ranging and want to avoid that, especially with them so young! The run will be really big when finished but for now I want them safely locked up. I don't have electricity out there yet either and temps are kind of crazy up and down over the next week with night time lows in the 50's and 60's. With 25 chicks I would think they could stay warm, but if the older ones leave the brooder then I will only have 7 babies in the brooder, which could get cold. What to do... what to do? Thanks for any advice!
