[/It's what worked for me, and the consequences of when my friend did not do it. When your a breeder you don't HANDLE each and every snake every day, on top of which feeding in the enclosure causes territorial habits.QUOTE]
I'm not 100% sure I follow you here. Are you saying my snakes are more territorial because they are not handled every day? Because that certainly isn't the case at all. Even our maternally incubating females are pretty easy to deal with.
It's not that I don't worry about cage aggression. It's not happening. Feeding in their enclosure isn't making them aggressive. And yes, if you are giving out information that I have found from experience to be inaccurate, I will point out why I find it to be incorrect. Over and over, I've encountered new keepers who are frustrated because their new snake won't eat and they've read/heard that they need to feed in a separate enclosure. It's a bit frustrating to see this myth keep going because I have seen it cause unnecessary stress for snakes and their keepers.
If it works for you, fine, keep doing it. What bothers me is that you are telling people their snake
will become aggressive if it is fed in the enclosure. It is not true. FWIW, I am not doubting that your friend's snakes are aggressive. I'm just doubting that feeding in the enclosure caused it, because I have done it with a pretty large group of animals over a long period of time and have seen no correlation between feeding in the enclosure and aggression.
