Breeding your hog is a very cool experience, although, it can be sad, stressful & irritating at times.
When your two hogs get along they will more than likely breed within a day or two. (sometimes it take a few weeks, but generally it happens quickly.) Some hogs take a few times being bred before they actually produce a litter & or keep a litter.
There are normally about 1-6 hogs per litter, although, it always is different based on the hog, the number of times its been bred, how its fed, ect.
Most times the mother deals well with the litter & can take care of them all with NO help from you.(Once in a while you will have to supplement a rejected hoglet..but its rare.) Its actually better not to even disturbe her AT ALL with her first litter as she may eat one or more of the young if she feels threatened.
Thistle was nice enough for me to handel her first litter the day they were born, but i would NOT advise that. I did it knowing the consequences.
Many people say to remove the daddy hog 3 weeks after they have been together as the gustation period of a hedgie is only about 36 days(give or take). You dont want the daddy in there when they are born, so its best to keep a record of when they were put together, & when she should be due, so you can remove him safely. Another sure way to tell if your female is expecting is to weigh her about once a week.
Be sure to remove the wheel & or any other toys that her or the hoglets could hurt themselves on. The wheel for sure needs to be removed as they will sometimes run in the wheel with their hoglet in their mouths causing injury to the hoglet.
The best time to breed your hogs is between the ages of about 4 months to 3 to 4 years. Males can be bred a bit longer or sooner, because the stress isnt so high on them.
Breeding your female more than 4 to 5 times a year can also add a ton of unneeded stress on her. So please breed responsibly & not just for money.
When your girly is about to pop (you knowing an approximate date from keeping records) you will want to move her to a nice quite, dark area where she will not be disturbed other than for feedings, watering, to check that shes ok, & to spot clean the cage.
You will know the hogs have been born when you can hear them quietly squeaking. You will want to provide a nice dark warm hut for her to have them in. I love using a basketball with a hole cut out of it. All the hogs seem to love sleeping in there & every litter Thistle has had, has been born in there. Something the hoglets cannot get out of will easy the stress level of the mother quite a bit. You will want to leave her alone & not touch the hoglets other than to put them back into the nest if they fall out.. but most times mom will do that.. (but its hard for her to keep track of larger litters.)
If you put one back in the nest be sure to use a spoon, rub it in the bedding first, then easily pick up the hog place it in the nest & be on your way.
You are not supposed to pick the hogs up until about 3 to 4 weeks of age.
