I have had 22 birds killed already this year (18 in one day). Besides the 18 that were killed in broad daylight, the others have happened when I've fallen asleep with the kids and not closed coops until 2 a.m. (2 nights! only 2 nights this has happened! and I've had birds killed each time). Obviously the [email protected][email protected] are in the run EVERY SINGLE NIGHT. Apparently they are just going over the 4 ft fence now. I am beyond sick and tired of feeding the local fox, coyote and raccoons. I am almost ready to give up at this point. Trapping works but we are just knee deep in predators. I don't feel we have a choice at this point but to move to a solar powered electric fence. For all of you that have elecric fences, do you still religiously have to close coop doors at dusk? I am planning to but life happens. If we installed an electric fence around our existing fence would it keep everyone alive if the coop doors were left open over night?
