Ok, now you need to know what the temp on the floor inside the box is. If it's too warm, they'll be running in & out. Honest, I'm not trying to make things difficult. Lol set a small room thermometer inside. I have an RF thermometer I repurpose for this. If you have a handy man living with you who does his own repairs, he might have one.
Temp is important bc if it's off, the keets can develop pasty bum, where a white plug stops everything up & they can't poop. This can be gently removed with warm water or coconut oil. The important thing is to gently wash it away, not pull on it. Pulling can cause internal injury and death.
On the flip side, it can cause runny stools, or dehydration.
The toe thing-there's always one. It probably won't hurt anyone at the moment, but it is something you want to keep an eye on as it can lead to cannabilistic behavior. I once had to amputate a toe bc the offender wouldn't leave it alone. I'd put shoes on him, get it healed upm & she'd start again (by this point they were grown). Weird thing was once I removed that one toe, she never bothered the others.
