Hello everyone! I recently adopted my first hairless rat (named Ophelia) who is just the sweetest little baby ever. I got her at 6 weeks old and now she's 7 weeks, and today I tried introducing her to my 5 other 1 year old girls. My girl Elise is the dominant rat and has always been a bit rough towards new babies, but nothing serious and no real aggression. She'll chase them around a bit, pin them, and power groom. There's always squeaks and squeals but never any injuries. But with my hairless baby, I was a lot more concerned about her because she doesn't have any fur to protect her! With previous intros between older girls and little babies, I've had easy success. Just a little bit of scuffling with Elise, but nothing the rats couldn't handle themselves, I've never had injuries during intros before. This time however, after a few minutes with the big laid-back girls licking Ophelia and sharing peas, Elise decided it was time for her usual baby bullying and chased her and pinned her. I heard some squeals and pushed Elise away from her. Then I noticed Ophelia now has an inch-long scratch on her back and a small bite or scratch on her face just below her ear. I put the rats back in their cages after that, and I'm really worried because I don't want her soft skin to get beaten up every time I do an intro with the others. Is there any way to make intros easier for a hairless rat, or will she just have to deal with some scratches and nips on her skin until they're all friends? Any tips are greatly appreciated!
