80g-feeder size?

My one month old BP is 80g, does the weight to age ratio seem right? Also what size mouse should I feed? I tried to find a chart online but they were all different and I'm not sure which one was accurate. What do you think? Thanks.

For babies 10-15% of body weight, so an 8-12 gram feeder.

Ok thanks, do you know what that would be equivalent to in mouse sizes? Fuzzy? Hopper? Maybe small adult? The one I got from the reptile store when I picked up my snake a couple days ago had fur all over, but it's eyes weren't open yet and it couldn't really walk that well. I forgot to ask the guy what size it was:confusd:

Mouse hopper or rat fuzzy.
