Hi Lisa,
First let me say......OOOooops!
The link on my site was directing to an OLD version of the breeding page.....It is fixed now.
I have found that BT's do much "better"

in the spring with a more complete brumation. (Better odds of female ovulating) Therefore, what I do now is a complete cool down to room temp, eliminating feedings entirely. (and housed apart)
Whichever method you try is up to you, but if you do cool them completely, feeding should be stopped a couple of weeks before temps hit the low point, so as not to leave undigested food in the animals system, which could rot.
If you leave the UTH on, be sure to check the temperatures so they can still digest.
