Rough Guide Timetable
Pairs are normally introduced following the
first slough out of brumation and mating is often initiated
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.
to 3 months at 10°C (50°F) - 15°C (59°F) is recommended but not
essential for successful breeding.|
||25°C (77°F) to 29°C (85°F) |
|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.
Normally around 57 days at a
constant temperature of around 28-28.5°C (82-84°F). Although
we have recorded 1 clutch that hatched in 45 days at this
temperature and have found no reason to explain it.
has been achieved with temperatures between 25°C (77°F) and 29°C
(85°F) but hatching would be expected to take anywhere between 45
and 105 days.

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