BML isn't something you buy by the pound, it's a mix you make and freeze. Priscilla's diet and Darcy's diet are also good choices. I
've done BML for years..but there's conflicting opinions on it , and I may end up switching my current pair to something else. Gliders that aren't socialized are HARD. I had a pair of sisters that I ended up letting a rescue take, well an individual with more time at the time than I had, as one ended up being a horrible biter. I'd say give them awhile to settle in with no handling. Bonding pouch will help,also. Check out,
www.worldwidesugarglidernetwork.com they have TONS of people on there that rescue and have experience with unsocial gliders,etc, that can help ya out. Good luck with them.
