I feed all of my bloods (and my BP, only have 1) in their enclosures, always have. I have never had problems and feel that the stress of moving them outside of their enclosures to feed causes undue stress and the thinking of feeding outside of their enclosure because of the snakes would associate that with feeding is an antiquated line of thinking.
