Hi everyone! I wanted to ask, how do I know the babies are getting fed enough? I read somewhere to weigh them every day, but is this a good idea? I feel like I would hurt them, they seem so fragile! Thanks for the help!
I would not try to weigh them. If the doe is doing a good job, the very best thing you can do is leave her to get on with it. Check them briefly once or twice a day, and try not to worry. Once they have open eyes and hop around, you can pet them and play with them a bit, and you can do more as they get older yet.
Fat, round bellies are a good sign (like in your photo).
Thin bellies, and loose wrinkly skin are bad (if the skin looks way too big for the bunny, that's because the bunny didn't grow enough.)
Once they have a good start (like yours), they have a good chance of continuing to do well. That is by far the easiest for you, as well as being best for the bunnies and the doe.
If the doe does not feed them enough, your options are very limited anyway. Rabbit milk is quite a bit different than most other milks, and baby bunnies are small and hard to bottle feed. So bottle feeding bunnies tends to have a low chance of success.
Should I expect another litter tho? The bunnies were left together a couple hours after she kindled, and I saw my buck mount her before k found the kits and seperated them
Yes, I would expect another litter 31 days after these were born, plus or minus a day or two.
Provide another nestbox at 4 weeks (28 days) from the date she kindled this litter, and check every day or so. If she has bunnies, move the bigger bunnies to another cage right away. If she does not have new bunnies, leave this set with her until they are 8 weeks old.
