I've been working on switching my youngins over to F/T, so I've been using live and freshly killed to help them make the transition. I've found that Sophie (Spider F) plucks her meal right off the tongs, dead or alive. However, Peyton (Pastel M) is more stubborn and likes to slowly make his way to his meal after it's been dropped in. Generally speaking, I try to keep them "head to head" to avoid a strike to the tail end, which could result with the snake being bit when being fed a live meal.
Hope that helps..
