Hello, at Easter time this past spring we hatched 2 male Rouens. We cared for them and when they were big enough we let them go in the 3 acre lake we have behind our house. They come back 1 or 2 times a day to eat but the rest of the time they are on or around the lake, even to sleep. They are always together never moving more than a few feet from each other. Needless to say our family has become very attached to these 2 little guys, we're able to watch them from the back window of our house. My question is; how do we care for them in the winter? If we need to provide them with shelter and a heat lamp will they know to come into it when needed? I guess it would have to be in our back yard because it's our subdivison lake behind our yard. They only come into our yard to eat then back to the lake they go very quickly like they're not comfortable away from the lake. Also, just out of curiosity, will our 2 guys always stay together or will they eventually split up. They're are no other rouens on our lake the only other "friends" they have are some passing through Mallards. Should we get more in the spring, Maybe a female or two? Thanks for your help.
