Rats are fighting!!!

[ScubaDiver007]

I'm a little sad for this post but mainly frustrated!
I have 2 female rats and one male. He knocked them both up and are going to have their first litters in a couple weeks. However, I found bite marks on the beige female and moved her out separately.
A couple days later, I found a large bite out of the back of the black female's back. Ugh... So I moved her to a hospital tank and she healed just fine.
Last night I put the females together, and I went to check on them this morning and the black rat had been nipping at the beige female quite a bit.
They are separated completely now but I really wanted to keep them in a group and am highly frustrated that I am wasting 3 cage spaces for what should have only been one main tub and one birthing tub.

Any suggestions?

Jess,

Try keeping an extra female from each of the litters and let them grow up with mom.. Cycle the male through when its time for breeding again.

Worth a shot and you will end up with two more breeding females..
