Yeah man I try my best to get all the morphs started on rat pinks, so on that I give you credit, if they will start on rats its better fer em... Most of my babies that wont start on pink rats, start really well on hopper mice.... The rat pinks dont move enough for some of em once they get a strong feeding response try the rats again...if you are only a month in you are still good dont stress it, they will eat when they are ready.... most of the time....
