I have faroese geese,their wings are clipped so you just walk them to where you want them. Generally geese start laying on Valentines day but the further north you are the later it is. Mine are just now pairing up and hopefully will lay anytime now.You cannot make them lay just provide the nesting areas and wait.I have mine free range and can imagine if geese are confined they will become aggressive. Their main diet is grass as they are Grazers and will become too fat to breed if allowed to on pellets.I would clip their wings and get them in their outside run asap, if you clip their wings really well(I take all long feathers off except the end few on one side)they should not be able to get over normal sheep wire.They need a lot of water to bathe in, more you can put in a stable,if they cannot preen properly they will not be happy. Mine even mate on water, they have a stream to swim, preen and mate in.They should only become aggressive when protecting a nest,perhaps getting them out into the field so they have more space and feed them flaked maize as they love it will get them more friendly and used to you. Geese are very family minded and loyal birds, when they are used to you they will follow you and your daughter around like puppies. Good luck Hermit
