Well as I said you certanly have to try the method I mensioned earlyer with your 2 other picky eaters. Temperature of rodent seems to be very critical for some BP since they seem to use their heath pits primarily and thus won't strike even if rodent smells strong. The other thing is that BPs are not much of a drinkers so for one the extra water on the rodent is actually beneficial for them and second a wet rodent is easyer to swallow than a dry one .
