My baby Red-Tail Boa's have not eaten in 21 days, advice?

well it's been 21 days since they last ate, one mae and one female. They were born May 14, 2011. They are housed separately, one in a 20gal long with aspen/reptibark and the other in a tub that's about 3'x2'x3' along with aspen/reptibark, i drilled holes into the top of the tub. Now i barely handle them at all because of some other answers i have gotten, however, i do from time to time take them out just to check out any sign of sickness, mites, etc. Both have large water tubs, i have tried to feed them every friday for the past 3 weeks and it's a no go. I tried to leave the mouse in with the snake for a couple hours (frozen thawed) but nothing. Now I don't know if it's me or if the snake's skin looks like it might be sagging a little, just sometimes when they are sitting a certain way but it might not be nothing ?..In the sunlight their skin is very beautiful and shiny just as it should be.. Also when they are being handled, both snakes are very active. I just need some information on what I should do? I don't want these snake to die or anything, please help. Also, i believe the temps are pretty good- with 80-95 in the day to 75-82 at night.
