I want to add one or two new hens to my flock of three. I am almost done with a new coop and thought that might be a good time. I was advised to quarantine the new ones for two weeks first though and to keep the new ones near the existing ones. I have a small wire dog pen, like 2x3 foot. Could I use that? Would I just keep them in that for two weeks, that doesn't sound like a good idea, maybe for one??? Or should I just toss them all in the new coop at the same time?
