Mixing female rats

[Mousey]

I found a female rat I really want but she is a medium large-ish size and the two other female rats I have are small medium-ish. The rat I want is living with other rats. So I was wondering what the chances of them fighting are.

Honestly, slim to none. They might go through alpha issues, but if there is an alpha already established with the two you have, they're going to pick on the new one. There is nothing bad with that as long as they don't fight until you see blood.

Introduce them on neutral territory (like the tub or your bed) after you quarantine the new girl for a few weeks.

Not very high, rats take pretty well to one another if they're still not full grown. And normally, adults don't mind the addition of a young rat or two to the group. You should be fine...if they spar a little, don't worry about it unless you see gaping injuries or very aggressive stances.

the sizes they have at the petstore are snake food sizes, so the medium rats and small rats are the same, probly related, just ones older than the other.

I agree with what everyone else has said. Girls are very good about getting along. I have my very large 1 1/2yr old male living with 3 of his sons who are around 7 weeks old now (sorry to lazy to double check age lol). Sure they are males but they do have quite a size difference .

You will likely have some dominance behavior as they try to figure out who will be boss.

Try this link. It explains a lot about introing new rats.

It's not in the nicest format, but it gives some good information.

I agree with what everyone else has said.Rats (especially females) will accept new rats into the colonies.There MAY be some fighting at first,but as long as there is no bloodshed,then they will be fine and work things out.
