HI I just got 4 Sebbies this weekend and i'm in love. I believe the lady said they are offspring of Holderread Geese. I have 3 whites and 1 Saddleback. Anyway i and new to geese, are there any good books out there on them? Supposedly i have 3 females and 1 male, they are 2 years old. Any help on sexing them would be very helpful. Also what do they like to nest in? right now we have a dog house with straw but they seem to prefer to sleep outside at night. I want to build them some sort of house maybe with nest boxes? We want to let them free range during the day but i'm not sure they will go back in their pen or house at night? do they go to roost like chickens? Any help would be greatly appriciated. BTW I LOVEEEE these geese!! lol
