Just tryed my little girl on two pinkies she wolfed the first one but the second one is still in there she is only two months old so may be a little soon for two but on one it dosent seam to leave much of a bulge.shes showing intrest in the second one but not taken it yet is she two young for two?
It really depends on how big your snake is. If one pinkie is no longer leaving a bump after a feed then it is time to try two, but two months is quite young to be that sort of size.
Assuming this is the little lady I sold you, all her siblings are still on one average sized pinkie every 5 days, a few on large pinkies I don't bother giving any of mine two of something unless I run out of what I usually give them, for example if I usually give one a fuzzy and I don't have any, it'll have two pinkies.
