Thanks peepsca!!, you have been realy helpfull!, but I dont know how well it would be with them free ranging the whole 40 acres, would they come back every night or would they go and sleep in the trees even if I keep them locked up for 6 weeks or more (the last ones I had I keept locked up for around 3 months and they never came back)so I am a littel woried about that.
I got a suggestion for ya. When you decide it's time to let them out, just let about half of them out. That should convince the free ones to stay close. Do this for a week or so, then they all should be fine............Pop
