thank you
@Preitler! i will do that. how do i ensure the babies are warm enough? They are currently in my basement which tends to be a bit chilly. i set up a radiator near their cage to try and warm up the area. the bedding they are on is paper bedding. are they supposed to be covered with it? as of now, they are uncovered for safety reasons as i don't want them to suffocate. also, they don't stop moving and wriggling. is this normal?
They cannot suffocate, no way, on the other hand low temperature can be a life threatening problem. They can't keep their body temperuture up when out in the open, with low temperature digestion doesn't work. They wriggle when they try to find a comfortable warm spot, not too cold or hot, and when they get disturbed. Normally you don't see anything of the kits until they leave the nest.
In nature, the nest is in an hole in the earth, consists of lots of hay with a ball of fur where the kits are in, and that hole gets sealed off with hay, grass and dirt except for a few minutes twice a day when the doe comes feeding. Most nestbox designs more or less simulate such a short tunnel (which keeps the kits from crawling out too), but most domestic rabbits lost the instinct to seal the nest of (only one of mine does it vigorously)
Since quite probably you don't have a stash of fur the cotton wool, dryer lint, or fur you can comb off other rabbits (if you can't pluck some from the doe, or if that would stress her) would come in handy. Anyway, as been said above, make a nest of soft hay, lots of it, it is a good insulator too. Also, the first thing kits start to nibble on is the hay in the nest, but that's not the concern for now.
You don't really need a nest real nestbox, an open cardboard box with about 4" walls will do. Check regularily after feeding (normally around dusk and dawn) that no kits are outside of the nest, they can be dragged out while latched on a teat.
