I am going to be getting some Pilgrim goose eggs next week and then some sebastapol eggs a bit later. My incubators are the little giant still air. First question.. How many goose eggs can I fit in one of those comfortably without over crowding? ....Do I "need" the fan kit? Is it essential? Ive done great without one with my pet quality call ducks. Id say my hatch rate on them is about 90%. I can get one if needed. .. In general, are pilgrims easy to hatch? Are there any problems I should look for? .....Any advice is greatly appreciated..
