Hedgehog Breeding
& Rearing Young
The hedgehog's breeding season lasts from about April until September.
The main period of activity is in May and June, when the nights are
warm. The gestation period for hedgehogs is about four and a half
weeks. Most baby hedgehogs are born in July and June. Females that lose
their litter for some reason are capable of having a second litter, but
they are unlikely to come after October. The average family size is
about 4 or 5, possibly 6 or 7. So, theoretically, given that a female
can have 2 litters a year, a female hedgehog could raise 10 babies in a
year. This is unlikely, as most of these baby hedgehogs would die. A
more realistic figure is that a female could raise 2, possibly 3 babies
a year.
When hedgehogs are born their spines are just below the skin, so they
don't cause their mother pain. They are blind at first, but after about
2 weeks their spines begin to show more, and their eyes open. Hedgehogs
also have baby teeth, just like humans. These fall out by about week 3.
Hedgehogs leave their nests when they are about 4 to 5 weeks old, and
they then must learn to fend for themselves. 1 out of 5 hedgehogs die
before they leave the nest.
