I bought a 1 month old 100% Heterozygous Albino Female.

My questions

1) How long after she eats will she poo? How long after in average?

2) Will a bp get long enough to be put on the shoulders like i see some people do with boa's i believe they are?

3) After a week + the feeding , So after i wait 10 days, how should i go with handling her, and the more i handle her the more she gets used to me or the more she gets stressed?
