I have some ~8 week old chicks. They've out grown their brooder, but aren't big enough yet to go in with the big girls. They are still about 1/4- 1/2 the size of them. Here's what I was thinking of doing. I made a fence inside the big girls run for the chicks they can not get at each other but they can see each other. For the chicks temporary coop I was thinking of using one of those huge dog carriers. The all plastic kind except for the vents at the top and the grate door. I think since it will be inside two fences nothing will be able to get at them at night. I will keep it away from the sides so no arms can reach through the vent holes. What do you all think of this idea? I'm trying not to have to build something else because they'll be able to go in the regular coop soon, just trying to figure something to get us by. These are the first chicks I've raised so still trying to figure it all out.
