I have a question about taking the babies outside on warm sunny days. When you take them outside, do you have a cage you put them in? is the cage bottomless? if it has a bottom say like chicken wire, do they try to eat grass and bugs through the wire? and how long do you let them out? if they are out, do you need to give them some grit in case they eat something out there? Ok, so its more than one question...lol. Please any advice is welcome.
