I have two 4x3x3 ft cages that were originally meant for breeding parakeets. I plan to have 3-4 chickens. They look like this: The sides are easily removed and I can attach the two cages together at a side to make one long cage or one square cage or one tall cage. The floor is wire with a slide-out tray underneath. How would you make them chicken-friendly? My current ideas are -remove the wire floor on both and use them as a chicken tractor -cover one for shelter, and add a shelf, perches and a nesting box -make the top(s) openable for cleaning -twist-tie the doors shut to prevent racoons from opening them thanks!
