Hi,

So I just recently setup 2 colonies of 1.4 rats in a rat rack and I think I'm having issues with getting them to breed. The guy I bought them from is reputable in the rat business and he told me all of the females he sold me are ready to go and have had litters in the past. All of the females are about 200-250 grams and the male is also about 250 grams. Whenever it seems like he's trying to breed the females just stand up on their legs and basically push him away. The breeder I bought them from said most of the time when they breed you don't even see it happening so I'm wondering if that's the case or if for some reason they just don't want to breed. I feed mazuri 6f and clean once a week to ensure everythings as clean as possible and they always have access to fresh water. Just want to see what an experts input would be because both of my colonies seem to be acting like this. The male chases them down and then they just push him away and don't seem interested lol

TLDR; do you ever see the males breed?
