I got 2 new week old chicks yesterday and put them in the brooder with my 12 - 3 week old rsl. One of the new ones jumped right in and started eating with the 3 week olds but the other one just kind of sat there while the others pecked at it. I took it out and put it in it's own box for the night until I could research the proper technique. It is kind of weak and not walking around much, but it did make it throught the night. Should I put it back in with the others?
