Inbreeding in domestic geese
I have a friend of a friend, in need, who has been feeding her family on Quail eggs, and who has requested a few of my fertilized goose eggs to hatch in an incubator, for future goose eggs for her family. My 4 geese are pets, are an original goose and gander (Toulouse), and a goose and gander hatched from them. During mating season this year, the mother goose paired up with her son gander and the father gander paired with his daughter goose. Are their any negative results of record to expect from such inbreeding in geese and how to respond, as well as the pros and cons of hatching such inbred eggs in an incubator as opposed to by natural means? Thank you very much for any clarifying information you are able to provide!
