Welcome Justine. I am in VA as well.
I had a first time mom nz meat mutt that looks like a beatrix Potter drawing, kindle 4 weeks ago. She had 12 healthy babies. Over the next week we lost 7 of them to what appeared to be her pulling them out of the box and then they would chill. 3 of them we never found at all. We aren't sure what happened. If it was accidental, intentional or predatory.
It might be an issue with the nest box design. If the box has a lip that is too low, healthy, active babies can easily "pop out," especially if they've moved their nest bowl toward the front of the box. Mother rabbits do not seem to have any instinct whatsoever to pick them up and put them back in. (I've never seen a rabbit that could/would pick up a kit to pull it out, either). The other thing that can happen is that, in a large litter, some of the kits don't get as much milk as they want, and they hang on when the mother is leaving the nest box; especially if the front is low, and they can end up outside the box that way.
There are two things we've done over the years to reduce pop-outs. One is to make the front of the box quite high (the mother will go in, even if the box has no entrance at all, with four high sides with an opening at the top). The other is to build the boxes with a bottom that slants toward the back. In this case gravity helps keep the kits in the back of the box where they are less likely to pop out.
We did have a Mini Rex doe that constantly re-made her nest for a week after kindling, and when she dug out the nest for her daily remodel, the kits went flying across the cage as she dug.
Fortunately, she was in my daughter's room, where they could be rescued.
I am also hoping to start quail in the spring. Are they as easy as everyone says?
I have found coturnix to be very easy, even easier than chickens (I do love my chickens!). They take so much less room, they're quiet and usually very peaceful. Our females lay an egg a day till they die (!) starting at 6-8 weeks of age till at least 4 years of age, assuming of course they've got an adequate daily light schedule. Their eggs are smaller than chicken eggs, but can definitely be subbed for them when the chickens stop laying (moult, etc).
Our Jumbo Browns were definitely a good food source. When my youngest daughter raised them for the 4-H Junior Livestock Market Auction a few years ago, they weighed an average of 1.2 pounds at 8 weeks. The kids call them "personal sized meals."
That's not much shorter turn-around than rabbits, but you can hatch dozens and dozens of eggs at once.
The only time we've had troubles with them is when they run out of food or water (they were my kids' projects!), they'll start to pick on each other. When the sex ratio is off, same thing. We could raise all males together, or one male to each 3-5 females, but if we had other ratios the males would hammer each other.
Raising them in wire battery cages with egg roll-outs was not ideal, as the quail tore their feet up scratching when they were eating. Since shifting to solid bottom cages and/or tractors (winter/summer), we've found that they live a lot longer and stay healthy and beautiful.
