I'd like to add guineas to my homestead, primarily for bug control. As such, I'm don't care that much if some fly off or get eaten, and I don't plan to harvest eggs for now. I would Luke to encourage them to come "home" at night.
I'm in zone 5a in northern Illinois. I have springs on and aroundy land, so I don't worry about water, but perhaps about how they'll survive the winter weather and dearth of forage.
What thoughts do you have for simple night housing and the necessity of winter feed?
