I have 10 RIR's that I let free range on my property. I've had them since the beginning of September and they are approx 22 weeks old. Five have just begun laying within the last 10 days. I live on 4.25 acres and most of the other neighbors also have good sized plots. Recently, the girls have been wandering off it seems. I go outside to look for them and I can't find them. Last night when I went to close them up for the evening, I counted only 9. I searched around and even left the coop open when into darkness, but she never came. No luck this morning either. There was no sign of blood or feathers, although I can't be sure something didn't get her. How can I get them to stick around closer to the house? I spread corn out for them when I let them out every morning and they're feed is in the coop. Should I leave them in there run for a week to let them get used to sticking around again?
