So, the stinkin rats got in! They didn't harm the birds, but I am in the middle of a complete re-do of my quail setup. I reinforced the bottom with hardware cloth instead of aviary wire and screwed it in with pieces of metal on the perimeter. Piled large rocks, then will be filling in with gravel so the rats can't tunnel under, as I want the hutch to be on the ground,like it was before, filled with dirt and gravel for a more "natural" feel. Tomorrow I will be reinforcing the bottom of the hutch, hopefully with more metal, if I can find it, as the rats chewed through the wood and around the hardware cloth to get in. Boy, rats are smart little guys. I'm gonna win this battle tho.
