Although it is different for each couple, for most of breeding couples, the eggs are substracted, bred and raised by hand.
By doing this, we take less risks for misbreeding from the parents, for damaged eggs, or for the litter to be killed in the nest.
It's our ambition to let the parents, in occation, breed their own eggs and raise their own litter. This improves the behavour of breeding from the couples.

The substracted eggs are put in incubatorhouse where temperature and humidity are very important.
