Just want to say, Lucky you for getting a feeding chart. I got Kaa from a local petsmart and they had no history whatsoever on when he last fed or what he fed or how old he was or anything...
as for the gender, from what i've read so far there's no way to tell whatsoever based on size/weight/markings/etc so you just have to wait until it's a little older and have it probed or popped. I would highly suggest against trying either of those yourself, regardless of it's age, if you aren't experienced as it could easily hurt your new baby.
Sorry I can't offer much for what morph, if any, it is. It looks like a normal to me. Did petsmart sell it as a normal? Usually if it's a known morph they will list it as such (with matching prices.) For instance Kaa is a pastel, and he was sold as a pastel and cost about $25 more. And they have a pied right now that i'm about to start selling my possessions for that is listed as a Pie Bald and has a matching price tag.
