how to switc adult male to rats?

just wondering if anyone has tips for me on how to switch my adult male bp over to rats from mice..he has been eating mice since he was hatched as far as i can tell..i got him from a breeder he is 700+grams

i read somewhere that using chicken broth could work? is that a good idea to dip the rat in a small amount of chicken broth? i tried putting mouse blood on a rat and leaving it in his tank but he just looked at it and then left it there..i think i really need to move him up a size from jumbo mice though as he is big and probably needs something more!

thanks for helpin

Live mice or F/T? Try a live small rat. If that fails, try a live ASF if you have access.
If it's F/T, try rubbing the mouse over the rat to get the mouse scent on it. At that size, I'm guessing you're feeding multiple mice each feeding?

F/t as i live in alberta canada..no live rats here. yes but id rather be able to feed one then acouple each time lol. i will try the rub thing and see if that works thanks.

Might try feeding back to back, smaller mouse, then mouse scented rat?
Figure if the food drive is still there try to take advantage of it:D;)
