it is. Just making sure you have one in there for them
Before breeding them, you should have switched them over. It can take months to do this, but it's essential, esp. for breeding.
when/if the babies hatch, when they come out, start them on pellets (add some warm water to soften them up a bit, they're too hard for the babies at this time.) and also introduce them to vegis and fruit chopped up fine. for a treat, let them eat some seed.
