I ordered instructions from Renegade Ridge on how to build breeder pens. I didnt realize it was for breeding, witch I am fine with. In the instructions in mentioned that I should build a recall pen, if using for breeding pen. 1. My chicks are going on 2 weeks. Will it be ok to put them in a **"breeder pen"** when they are ready to leave the brooder? 2. Why would I need a recall pen? Thanks again for all the help!
