Hi Frank, I do it a similar way to Gregg like i think most do, 3-4 weeks after brumation they start going at it, I do however not put my hognoses in Fridges, I find turning the heatmats off for 6-8 weeks and leaving them at a room temp of 65-70F works everytime for me.. But i do have a few females that have bred at really weird times and that have not gone through brumation..... Oddballs as with a few of my males that will breed a female without brumation lol ANYTIME of the year, One thing i do know is Hognoses are full of surprises sometimes. Cheers Lance
