haha, i know, they are little monkeys, aren't they? they start picking up proper food when they're only a few days old, it's amazing! i probably wouldn't give them any dried stuff either, until they're about 6 months? having said that, my lot did get fresh leaves (i used to feed a small amount of fresh leaves to my chins as that was recommended by a vet when i got my first boy) and were perfectly fine. i did stop feeding everybody fresh leaves when mae nearly died of stasis - it had nothing to do with fresh veg, she's a rescue and i didn't want to change too many things in her diet at once so she didn't get as far as leaves but her being so sick really scared me and given that fresh leaves can contribute to gut problems, i thought it wasn't worth the risk.
general advise for kits is do not give any treats etc until they're 6 months old. i think dried veg is a 'treat' type of food.
it must be horrible. i'm lucky i got to keep all mine but i know i would it incredibly hard to give them away.
