Adopted a new BP but feed questions

got a BP from a lady on craigslist who claims she/he will only eat male mice and only certain color mice (i.e. black body with white or grey spots) anyone ever hear of this before?

NO THATS KINDA WEIRD MAYBE SHE MENT THATS ALL SHE GIVES IT:confused:
IDK

Some Ball pythons have been known to imprint on certain color prey items. Generally speaking, pickiness increases with poor husbandry practices. If you get the snake into a night tight enclosure with two tight hides and leave it completely alone, it may very well eat anything you put in front of it.

Thanx i thought it was really strange he has not eaten in like a month but he has not appeared to lose any weight. he was eating live rats but i am gonna try to switch him over to F/T

:::::UPDATE:::::

I offered "SPOCK" (our new snakes name) a frozen thawed mouse and he struck it within 1 minute of putting the mouse in the enclosure. i went with a odd color solid pattern and he hit it hard and fast.
about 3 mins affter the first mouse he hit another and seemed verry happy

i'm so happy he ate and ate well
