From what I understand you could create a breeding 'off season' by brumating your snakes for a short period. If they are ready they will start to mate very soon (although some people leave them overnight or for a couple days). My observations they hook up within 0-30 min and stay that way for a while mine were like 30-45 min. Generally brumation starts sometime in Nov. ends Feb., the snakes are warmed up fed..., after their post brumation shed if they are fit they will be bred, or some may wait until after the next shed. Just a side note not all people brumate. So actaul breeding takes somewhere between March and June, give or take people starting earlier or going later. Many adult males will go on a hunger strike form Feb/March -May/June eating very little if at all and having only one thing on their mind.
All of this is based on the fact that your snakes are old enough and big enough to breed??? this is just the tip of the iceberg on breeding, hope this helps, susan
