I started with 10 hens. Two Rhode Island Reds, four Plymouth Rocks and four Buff Orphingtons. I am down to 8 hens. One Rock died mysteriously....just fine one day, dead the next. Lost a Rhode Island Red just a couple of days ago. Flock was all free ranging, she was with flock in the afternoon, come evening when I locked them in their coop for the night, she is gone. Just disappeared, no evidence left behind. Feathers or nothing.....either a hawk or some other sort of predator I would imagine. So, I have come to the conclusion, in order to keep the rest of the flock in tact, I need to keep them penned in their coop since I do not have an enclosed run for the to be outside in. Will Orphingtons, Rocks and Reds do well being cooped up? I really don't have a choice if I want to keep the rest of them alive. Really can't afford to build an enclosed run for them right now. Any suggestions? Have noticed since I have penned them that their laying has dwindled. Out of 8 hens I am getting about 3 eggs a day, doesn't seem right? Does this have to do with their being caged? All hens are under 1 to 1.5 years of age.
