We have some 6-week old babies and we built them a lovely British-styled chicken ark. They roost upstairs and run around in a fully wire-enclosed run downstairs. We put them out there this week and they're SO happy. We adore these chicks, by the way. They are SO much fun to watch. They're our only pets. But . . . last night I was awakened by this terrible sound. This morning I saw, to my horror, that two very large, free-roaming dogs had literally BITTEN THROUGH THE WOOD of our ark!!! They came back for another try in the daylight and I ran them off with a big stick. LUCKILY, they didn't make it in. Everyone is safe. I alerted their owner and she (who is a very nice lady, by the way) said they'd keep them tied. BUT, we don't have a fence and she doesn't have a fence and it would only take one slipping out of its collar before it was right back over here. So, thoughts on how to keep the girls safe? I don't want the dogs anywhere near them. I don't want the dogs in my yard at all. What kind of deterrents have you found useful.
