After reviewing Dean's schedule, I personally see nothing abhorrently wrong with it. Every 3 days might be a bit excessive for me, but we're talking about pinks here. There isn't much nutrition in them, as Preita has said. Once you get them onto fuzzies, something with more nutritional value they grow better. So why screw around wasting time they could actually have spent growing?
But he's not carrying on this schedule onto the larger food items, but is knocking back the frequency to every 6 days, which is what I do around here typically. Most of my hatchlings who're still on pinks have digested it in a day, and pooped out in 2. So why wait so many days before the next feeding. And the last time I checked, there are only 1 set of 5 days in a week, so it might as well be every week.
Unlike Preita, I think snakes are like dogs in that they could literally eat themselves to death. Once they've got food on the brain, that's all they think about. Which in the wild, its natural to gorge yourself when the vittles are plentiful to fatten up for potentially lean times. Its THIS mechanism that most people use to their advantage and the snakes disadvantage. They're just doing what comes natural, despite being captive bred and living in an aquarium. Despite the mutt genetics and eons of removal from the wild, my dog, if she finds a deer carcass, she's coming home "fully loaded". Hell, I do that when I know I'm going to my favorite down-home cooking establishment.
I don't think there is "proof" regarding either method (maintenence vs Roys) as to if its actually detrimental to the health of the snake in the long run. Power-feeding to me is carrying on such an aggressive feeding schedule with ALL sizes of food throughout the snake's life. And that common-sensically would be detrimental. But doubling up and feeding more pinks bugs you?
Joe Pierce has already voiced his opinion on the matter, and he is a very respected breeder. I don't think Joe would ever do anything that compromises the health of his animals. His animals are the healthiest I've ever ordered from someone. Although I think Rich feeds on a more conservative regimine, as I remember him saying he prefers his snakes to grow slower and doesn't usually breed until they're 3 years of age, even if they're the size to do it at 2 (then again Rich has entirely too many snakes to feed more often I'd think). So I think it all boils down to personal preference. And that is something you just can't change, you just have to accept it.
I personally think you need to find a new hobby or something, stirring the pot has gotten old. At the very least, all I see of Roy is his now expensive pink orders. If you don't order snakes from Roy in the future, I'm sure its no skin off his teeth. I wouldn't do business with you either considering how outlandish your attacks have been on the forum. So I guess that just leaves more hatchlings for me in the future, so that when they get here I'll "cram food down their throats with a chopstick" every 4-5 days like all of my own hatchlings get.
