Recently I purchased six 5 week old female coturnix quail from a battery farm. I wish now I had 'rescued' more. They have settled really well. When my dog puts his paws and nose close to the bars they don't bat an eyelid (and he's big) when I open the door they go crazy. I'm currently keeping them in a very large 98x86cms Guinea pig cage with hiding places. The only problem I've had is the new water bottle. The hay is always wet around it and needs changing every day. I plan to build a large off ground hutch and detachable off ground run for the backyard. I'm researching what grasses will grow in 4 inches of dirt and still survive the quail. I want the run to be as enriching as I can make it. The question is wire floor or solid for the hutch. I live opposite the sea in an area known for mice and rats. Other than convenience for the owner is there any advantage to wire. To me it feels cruel. Won't their feel hurt after awhile. What would be the best size of wire. Would rats eat through a corner of a wooden floor to gain access or grab a leg through the wire. Any and all suggestions would be appreciated for my new quail house.
