Yes I'd consider leaving it as a dirt floor, since that's the easiest way to handle it.That was an excellent write up and modification, thank you! it seems the easiest and most spacious so far. I just need to board up some walls, remove some insides & relocate the ramp & roosts. Maybe it’s not easy as pie, but seems doable and I’m excited to right my mistake. Do you think I can leave it as a dirt floor? id love that because deep bed method seems like the way to go. It will be inside a predator proof run. I could even pick it up and move it to another spot in the run.
You shouldn't need ramps as long as there's room for the birds to get up and down on the roosts by jumping.
