BirdBrain, I have six geese in Nome. Their barn is 10x12 so they have a lot of room for the winter. The pen is chain link panels I used to have set up for my dogs and I give them quite a bit of space most of the year but for deep winter, they don't need much room at all outside. I think it stays cleaner this way, too. My two eldest are an Ebden and a Toulouse (girls) and the four younger are a year and a half old American Buff's (2 each of goose/ganders). I know things will change this Spring because of the two ganders so I have room to section off the barn and the run because the smaller gander will not tolerate the bigger gander once they decide to really pair off. I'm going to eventually butcher the smaller gander because everything I've read says to keep the nicer geese for good temperments and the bigger gander is always good with me. The geese won't tolerate the ducks in their area either. They are housed/penned side by side and the nosey geese are always talking about it...("come here, lemme eat your feed, come here, lemme show you who's yard this is..."
I don't like housing the ducks w/chickens cause the ducks love water way too much and empty it out while making a mess and then the drakes chase off the chickens when they are on the ground- stress. I like having ducks and geese, the Cayuga's and the Magpies (one crested and one not) are HUGE in their second year, people think my ducks are "geese" and my geese are ???
I don't worry about predators at the edge of the tundra/town because the geese can be very loud when they announce something and the dogs then become alert and can be loud, too, in the house so I have time to run to a window or run outside, night or day. Its a different story at my cabin though, I have a "roll around coop" built on a trailer that I either shut them in at night or again, the loud announcement, the dogs in the cabin alert me, too, and if there is no moon or no sun
I drive down in the vehicle with the dogs since the cabin is on a small hill and the pond down below. We have fox, bear, moose at the cabin but so far no problems I think because I've got four weimaraners and 2 golden retrievers, a wolfx and an Australian Cattle dogx to help me out.
