Hi ! I have been raising heritige geese for a while now,and I want to get something more productive.So this year I am getting some white hybrid geese for meat and some grey hybrid geese for foie gras.I have read that by crossing a grey female with a grey male you will get a bird with a super fast grouth rate and a very good weight.So I want to cross the two breeds in the search of the supreme meat,foie gras & eggs hybrid goose.I have spoken to a person that raised both types and both hybrids lay very well up to 110 eggs per year,up to 55 eggs per laying period(they have 2 laying periods-spring and autumn).And I am just curios what colour do you think the cross between the two will be ? I would prefer a bird thats mostly white,only with some gray on the back,I want them mainly white cause of the plucking,I want nice white down.What color do you think they wiil be ?hopefully the one I mentioned earlier.Goose breeders tell me your opinion !
