I haven't gotten any yet. I do have a time set up though I will hopefully be picking up some chicks in the coming week or so. I want to make sure when it is time to transition them to outside that they are safe as can be as they will be pets and for the occasional egg. We have two man predators. Raccoons and Cats. We have a large chain link dog encloser. Very very large, I planned on setting this back up and using it and building an encloser inside of it for the night time and nesting, ect. It is very tall but I still am thinking I need a roof because both of these predators can climb. Now sheet metal? Wood? I am unsure... I was thinking a tarp but they could rip through that most likely. Could I place wire fencing / chicken wire across the top - secure that and then place a tarp on top? Also this dog run / chain link cage I cannot fit my hand through the wholes in it but I was reading around a bit and it recommended having it wrapped in chicken wire as well so that animals couldn't squeeze through it. But I honestly don't know what kind of animal could? I also see people who don't do it - they leave it be. Suggestions? I also plan on placing bricks / large rocks around the bottom so that an animal cannot dig under it into it. Any other suggestions or suggestions to help me further my above thoughts already would be greatly appreciated!
