I have a little mixed flock; 8 hens (2 rhode Island reds, 4 plymouth barred rocks, one black australorp, one buff orpington) and a rooster we rescued with the name of Dr. Love. Not sure what his breed is, but he's a nice one, and not rough with the hens. Anyway, the buff orpington, who has the super original name of Buffy, has just started spending all her time sitting in a nesting box. She's not on eggs, so I don't think it's that she's broody, but I don't know. Every morning when I feed and water them I let them run around on the lawn. She used to LOVE to do that, but now I have to reach in and pull her out. Then she'll eat and drink a little, but she goes right back in. It's been 2 or 3 weeks now. Any thoughts?
