I was gone today the whole morning and early afternoon, and when I got back one of my 4 week old chicks was gone. No trace at all. I stood there and counted for twenty minutes to make sure... I compulsively count them every time I go in the coop, so I know all were there when I let them out of the coop into the yard this morning. The yard I have is 6 foot 2x3 welded wire with the bottom 2 feet covered with poultry netting and an apron of poultry netting. For the top I strung a bunch of wire back and forth between all the posts... but I'm thinking it wasn't enough (um duh, right?). That would be a hawk, right? But my run is huge- it's 30 x 30, and the idea of fully enclosing it seems overwhelming, mostly financially. How would I support something? For now I took all the extra poultry netting and hardware cloth I had and kind of laid it over the top of the wire, but it only covered about 1/4 of it. Am I right to suspect a hawk? Any advice at covering a run that large? I'm going on a five day vacation in a week (someone will be coming over to feed them and lock them up for the night), and I want total coop confinement to be the absolute last resort.
