I was old to keep them confined in their pen for 5 months before letting them out because they will wander off and get lost or run away. I"m told they aren't smart at all. I have 7 and I plan to keep them around for eggs and the others can wander around and eat bugs. If they make a nest and lay their eggs where I can get to them all the better. I'll just let them do their thing and just collect the eggs. We get ticks real bad here in the spring. And some kind of mite that we get attacked by. We counted my bites as I was getting dabbed with the pink stuff and I had 154. That was in the spring and i still carry the scars because they itch so bad.
