My buttons are still in the brooder at three weeks old, but I will pair them off and they will (each) live in a tubby cage to start. Link above.
I got the 28 " long one. I'd like a larger cage but don't have the space right now or the funds.
I like the Tubbies because I can put hay, shavings or sand and that won't fly out so much as in a basic cage, yet they have air circulation and are secure.
The tubbies will work great. I can't afford tubbies, so I made my own. I used super pet cages in the begging. But, at $20.00 a wack for a pair oche....
