So... just an update. All of the kits are gaining weight and look to be fine at this time. I ended up just giving them all back to mom, as the two I was fostering out didn't seem to want to feed off of the foster mom. There's no more fighting and they're all sharing very well. I'm still supplementing the smaller ones and rotating every once in a while to make sure that everyone is getting an equal opportunity. Lets hope that this turns out for the best.
