Rough Guide Timetable

Pairs are normally introduced following the first slough out of brumation and mating is often initiated quickly.

After successful mating it is normally around 1 month until the female completes a pre-lay slough. A gravid black ratsnake will not normally go off her food but it is advisable to reduce the size of the food offered until after laying.

From pre-lay slough to egg laying is approximately 5 to 10 days.  Black Ratsnakes do not normally complete a post lay slough.

Incubation time is approx 2 months.

Brumation 2 to 3 months at 10C (50F) - 15C (59F) is recommended but not essential for successful breeding.
Incubation Temperature 25C (77F) to 29C (85F)
Expected Number of Eggs Between 5 and 44 eggs per clutch have been recorded but between 6 and 16 eggs per clutch is more usual.
Incubation Days

Normally around 57 days at a constant temperature of around 28-28.5C (82-84F).  Although we have recorded 1 clutch that hatched in 45 days at this temperature and have found no reason to explain it.

Successful incubation has been achieved with temperatures between 25C (77F) and 29C (85F) but hatching would be expected to take anywhere between 45 and 105 days.

Incubation method

See our Guide to Incubating Snake Eggs.

Caring for the Female

Multiple smaller food items should be offered whilst your female is gravid. Gravid females do not normally refuse food whilst gravid until after the pre-lay shed.

Immediately after removing the eggs we place the female in a tub of fresh luke warm water to clean the substrate, particularly from her eyes and mouth and also to give her the chance for a much needed drink.   At this time we offer her a single smaller food item and continue with smaller food items a few days later. 

We recommend feeding your female heavily for the first month or so after laying.

Hatchlings Black ratsnakes will complete their first shed around one to two weeks after hatching. In our experience, they do not normally present too much difficulty in taking their first meal.
