Hi, my three lovely geese and their gander have made a nest, all three girls are laying in the same nest but none have gone broody so far. I'm concerned what will happen if they all go broody at the same time. Do I need to build 2 more nesting boxes and put eggs in each to encourage them to go in different places? I have read that geese pair bond, does this mean the gander will only be mating with one of the females? I know these are probably really basic questions, do forgive my lack of knowledge on all things goose.
