My Ambilobe babies would eat nothing but ff for 6 weeks! I tried everything to get them to switch to crickets, but then realized that ff were actually cheaper to feed them for the quanties that they were snarfing down, and I was only having to feed 27 babies. Veileds go to crickets pretty quick, they seem to like the meat and they grow quick. Bad thing about ff is you end up finding ff wandering all over the place no matter how careful you are putting veiling, tops, screening, etc. all over the bins. What a chore. Thank heavens for hand held vacuums.
