I had been using paper towel on top of newspaper and have been having to change the paper towel many times through the day. And they were eating their droppings I was also having trouble with them pooping in their water dish and having to clean that several times a day too. They were eating the shavings so I couldn't just go that route. So I went ahead and used the mesh idea and I love it! It is probably a bit bigger mesh than it should be but that's what I had available. They don't seem to be having too much trouble with it. And then I moved their food dish away from their water dish and now they aren't pooping in the water tray it as they eat from the other dish. And I put in thicker roosts and they LOVE them! Three or four of them will squeeze on one branch at a time and go to sleep. It is so adorable to see four little heads curled up in sleep at the same time on the roost They are 8 days old today!
