Hello! So my chicks are about 2 weeks old right now and I was wondering when I'd need to move them into a bigger container and then after that when they'd need to go outside. There are seven of them and they are currently in a 50 gallon Rubbermaid tote (43.81" x 22.81" x 18.16") and for now of course they're doing fine in that. However, I don't know how big these guys are going to get (assorted heavies) so I'm not sure when to be prepared for the next step. Any information would be appreciated because I'm just overall clueless. I have a plan for where they will be going once they're outside full time but I don't know how it works in the times between brooder and outside. Thanks so much!
