my new babies !

Hi all! I am told these 3 are 5 weeks old. I am assuming by the lack of testicles that all 3 are female. Just hoping to get your thoughts on what gender these babies are. I am fully prepared to keep seperate, I do NOT want to breed rats haha. Thank you!

My new babies to help me deal with the loss of Tino ,Sammy,and Happy in 3 months and all of different issues . Was really hard !
