I usually open the coop at six in the morning and close at six in the evening everyday. Is it too much?
Now I will have to keep my only baby hen left inside the coop and never let her outside until at least next summer when she will be grown up and able to escape these predator attacks.
Now the only thing left to happen is that an ill-intentioned person opens coop and steals my only hen left because if this happens it would be really bad.
Now this hen is alone in the coop it's cold and heavy rain and thunder outside & quite scary for her to live alone and together with this predator no one knows who this is. Just 2 or 3 days ago I saw a fox nearby but I doubt it would came in my home near the coop so I'm oriented on the neighbour's cat/dog or ill-intentioned person suspicion.
P.S. I think killing foxes with your rifle just because you lost three hens is quite borderline.
