Cream, growing up breakfast was alphabits cereal with straight cream on it. Nothing like it!
Guineas will do ok alone but they love to chase each other so yours may take to chasing other birds, especially if it's male. Last winter I had two, thanks to the coyote. They needed more. This year I have 3 males and 9 females and they are doing great. Not picking on chickens and getting along.
I have been amazed by the ducks. First winter with them and they'll go out in anything. They wade snow and I find tracks all over where no chicken had dared to go. Are ducks smart enough to go in when needed? They have a "duck box" in the bottom of the coop where they sleep.
Well I have to shovel this morning, very wet snow that I'm not looking forward to.
My ducks hardly ever go inside, even during the worst weather. They know how to use the coop, since they lay eggs in a corner in there. But even during snow and wind, they often sleep outside. There is still some open water where the sump pump discharges water, so as soon as I open the run in the morning, they take off like little penguins to splash around (since they're Magpies, they actually look a bit like penguins, too). If snow gets deep, they belly slide.
I think ducks are better with the cold weather than chickens. The ducks did this last year, too.
