I am hoping to keep 3-4 of the chicks that I hope to be hatching on 4/27 (my first hatch, from eggs i collected from my girls). I have been advised that I should keep them seperated from the grown birds for at least 5 months in order for them to be about the same size, not get hurt by the rooster, not be exposed to diseases that the grown birds might be carrying, etc. I guess I will have to build another small run and another small coop. My question is how old do the peeps need to be before I take them outside to the coop and run? Any suggestions?
