I have 4 ~6mo buff orps who learned about 2 wks ago that they could fly over the 7' fence that makes up their run. I let them free range in the yard anyway but now they're out their whenever they want, not just when I let them out. At night they have been roosting on the top of the fence and in the small tree/shrub next to the run. What should I do as its getting chillier at night and I don't want them loose at night. Take them down and manually put them in the coop? I shouldn't let them stay out there loose all night, right? Plus how do I make the nesting boxes appealing. I haven't gotten any eggs yet and I'm worried that perhaps they're laying somewhere in the hard or their run and I'm not finding the eggs? Lastly, since they've been letting themselves out willy nilly they sometimes get harassed by my dogs. So far no ones been hurt and I don't let them out together unsupervised, but could the dogs be stressing the hens out of laying? When they're in their run the dogs don't pay them any attention, but loose the chickens are fun to chase. :-/ TIA!
