Just had an idea but wanted to see if it would be safe. While I can't expand the brooder since it is a dog crate. It is tall so I can add a "loft" area in part of it to give them a bigger place to jump up to and in a way "expand" their brooder space. Would this be safe for them? I don't want them getting hurt trying to fly down or any other way. The crate is 42" long and 30" high. so I could maybe do like a 15" loft which will give them like 27" of space to jump down. and would add a 15"x27" 2nd floor.....
