Snake Breeders, Do You Feed Live or Frozen/Thawed?

I always feed f/t. It is unlikely that constricting the live animal gives the snake all that much exercise. My adults all grab and constrict f/t mice as if they are alive and have often constricted for several minutes, regardless of the fact that the animal is long dead. Since my cornsnakes are close to 5 ft., and my one male is over 700 grams, I don't think your idea of growing bigger snakes is necessarily supported. I feed every 2 weeks, so my snakes are lean. Overfeeding causes fat snakes. I take my breeding females out several times a week for "excercise" during their pregnancy and they all lay eggs perfectly well. Most of us either feed in the cage, tub or in a feeding box. Even if you fed live, the animal doesn't have to go far to get the mouse....therefore, the benefits of exercise are nearly nil. I can illicit the same amount of exercise by offering with tongs and making the snake "hunt" the mouse. As far as loss of nutrition. I get my mice live from a local supplier. They are ged and frozen soon after. They are usually consumed within a couple of weeks due to the large amount of snakes I have. I don't think they lose an appreciable amount of nutrition during that time, and my snakes are certainly healthy and strong. The dangers of feeding live...even supervised is a fact. I've seen the aftermath of poor strikes on a large mouse or rat that's resulted in eye loss and damage to the nose. Even worse is unattended feeding where the mouse or rat has eaten the snake instead. The only time I experienced egg binding was when I didn't take my gravid female out for exercise. Otherwise, they lay everything fine and without a hitch. I know large scale breeders feed what's convenient. Live, stunned, pre-killed or f/t. I'm not large scale, but f/t in my book is the way to go. My babies are all started on f/t and I won't knowingly sell to someone who will feed live. I won't risk my animals over the perhaps infintessimal benefit of live. I just don't see any benefit at all myself.
