So I googled a Size chart and came up with a few examples that say a 7 month old ball python should be between 300-600g... my snakes are way under that. I trust my breeder cared for them, but i know he only fed every week and a half.

Spaz is 95g and he did finally eat last night. He was born Nov 2013 per records
Dinker is 150-160g Born Oct 2013 per records
Sheeba is 150-160g Born Oct 2013 per records
Pagani is 169g Born Oct 2013

I will be getting a scale very soon, but i wanted to get some opinions. All but spaz are very docile and very intrigued by their surroundings. Once the kids go to bed spaz is a lot better about wondering around but he gets scared very quickly.

Should I start feeding them more often? Maybe every 5-7 days? Try to get some weight on them? I am hoping to breed them but at this rate it will be 3 years. They in theory should be ready this fall or next spring. Right now it seems i'm on track for the 2016 season.
