Make a lot of rabbit pie?

Remove the male, obviously.

The problem is that your doe was still with a buck after she got pregnant the first time. It is possible for a doe to be carrying 2 litters at the same time as there are 2 lobes to a doe's uterus and she can get pregnant separately on each side. A pregnant doe should always be quiet, by herself so this doesn't happen. It is very hard on her body to go through 2 pregnancies. I don't exactly know what to do as it depends on the condition of her first litter and how far apart in age they are. If we are talking weeks, it would be better to remove the older ones and try to foster them unless the second litter is so weak, it might be the kind thing to let them go. Tough one. But I can't say it enough. All breeding rabbits should be in separate cages all the time, unless a planned breeding is taking place.

a lot of work cleaning...

I'm in the same boat as you... the doe I'm fostering (a Lionhead) came to me pregnant, since she was placed in a hutch with bucks before coming to the shelter. I got her on July 1st, and she had 3 healthy kits on the 17th. Now she is big in the belly again (easy to see, since she pulled so much fur for the first nest), and I can see wriggling! Here we are on August 1st, and I suspect there will be another litter in the next day or two. Luckily I saved her old nest box (giving only a little of the old fur and straw to the 3 kits in a clean box they could get in and out of), she seemed interested in it when I put it back in her enclosure. Also resumed the '1/2 fruit-flavoured Tums' twice a day, to support against calcium depletion, a common problem during bunny-birthing time. The new babies won't be out of the nest for about 14 days or so... giving the first litter a healthy head start, since they've started eating solids already. It's normal for rabbits to have more than one litter at a time, since their physiology is adapted to it. Hard on the caregiver, but I'm sure she'll do what comes naturally. Give her lots of quite space, fresh water, produce and unlimited hay (not alfalfa, it's too 'rich'). Dandelions and spinach are high in the vitamins and minerals she needs, too. Hope this helps... best of luck!

Buy extra potatoes and stock-up on gravy granules.
