So my notes on this are as follows:
•Big agree with having a veterinarian on hand before ever beginning the brumation process.
•As far as timing goes it honestly depends on the breeder and environtment. Some will start brumating their snakes in October-January, some will start December-Feburary. Whether you are in a cooler or hotter environment can also play a role in this timing decision. For me personally I dont brumate until December because it takes forever here in SE Texas for it to start cooling down and entering the true winter season, and once they are done we are already practically through all of our winter weather aside for a few off days.
•For Hognose snakes as a North American species they can brumate at 45-55°F. You don’t want to go any lower than the minimum and you will want to preferably stay at 50°F avoiding major fluctuations. If you go higher than 55°F I don’t think it would be terrible but you also don’t want it to stay above that for too long, it may disrupt the brumation process. As far as opinions on whether or not to brumate is so-so, I personally have successfully bred Kings without any brumation besides leaving the lights and heat off for 2 months but they are a South Floridian species that really don’t experience temps that other areas of the US do. Some people end up with bad luck and majorly slugged clutches from not brumating, I honestly think it comes down to the species and locality. For your Hognoses I’d say its fine to brumate.
•Again a big agree with the article is to make sure your Hognoses are ready to brumate. If they aren’t at a good weight and at optimal health brumation can kill them. Make sure they don’t miss any meals before they start their prebrumation fast.
•For safety reasons I personally prefer to fast my snakes 3 weeks before brumation just to make absolutely sure they have nothing left in them that can start to necrose in their digestive tract while they are cold. I will go through and spot clean every day until I see no waste passed at all from my snakes. It may be overkill but my snake’s health takes top priority.
•Once that is done shut off their heat sources as the article states. Any non-heat lighting could also be turned off 2 hours earlier than the norm, this simulates shorter days and may encourage them to enter brumation faster. Give them a week with this routine, this will mark the beginning of brumation.
•Have a container ready for them to brumate in. This doesn’t need to be very large at all, they won’t need as much space as they will very sparsely move outside of getting a drink of water. Let it be a reasonable size though, it wouldn’t be comfortable for them to be cramped and it needs to be big enough to allow for a shallow water dish. Add enough substrate for them to burrow in.
•Once they are added to their brumation chamber do not add them to the chamber being already cold. Add them with the chamber turned off and at room temp, and then turn it on to let it gradually cool. Once you are at this stage all you really need to do is check up on them once a week, top off any lost water and look them over for just a brief moment to make sure they are good and healthy still. You can weigh the container if you wish, you’ll just really need to keep track of those weight parameters and make sure you don’t accidentally miscalculate something.
•On the article it states to not let the temps get below 38°F… I personally would say not to let those temps drop below 40° at the absolute minimum. Anything below that might be dangerous.
•I also wouldn’t reccomend immediately taking the container out of the chamber once brumation is “over” and placing it back in their enclosure. I’d do the reverse of the beginning of brumation and let the chamber warm up gradually with the power disconnected and the door open for a day, and then reintroduce them to their enclosure. Once they are back in I’d gradually increase their temps from room temp back to their normal temps over the course of a week to avoid shock from sudden temperature changes. Once they are warmed back up they can start on their regular feeding schedule again.
