Have you been raising them long, or are these your first?
These are my first ones, but we got some juvenile buffs (a kind of golden chicken) so I'm not new to the whole process.
Wolfy: Dude I'm going to move them out when they get bigger. Right now though they're very temperature sensitive. Plus, I'm not married, or have a girlfriend so I pretty much get to do what I want.
Tsnenta: The marbles are in there because when they're that little and clumsy they can actually fall in and drown. So you put a few marbles in the dish so that it's less deep but still lets them drink the same amount of water.
