baby buns on the move

my baby buns are two weeks old today and tonite i saw on of them leave the nest and walk round the hutch then go back, not they are startin to move about are they anythings i should/shudnt be doing. i no i have to stop putting greens in for the mum so the babies do not eat them but is there anything else, are they ok with hay my buns have timothy hay? thankyou

They will already be nibbling hay. The number of pellets that need to be available will also need to be increased too as the kits start to eat more. Don't have any salt licks or anything in there, if you do.

Just basically keep the cage clean but make sure they know where thier base is (where the nest was), so they know where to go back to.
