I lost a chicken to a predator this winter and have since upgraded my security to the point of ridiculousness.The two remaining chickens are very happy together and produce enough eggs, at least in spring and summer, for our two-person household. What are the chances that both chickens make it through the winter without mishap? I would hate for one to be left alone all winter in case of mishap, but I also don't want to have to build a new coop for five chickens after raising the obligatory three chicks this spring. I wouldn't mind building another coop next year, but we've only had this one for two years, and I'd hate to consign it to "grow-out" status so soon. What do you think? Should I prepare for the worst and buy more chicks, or should I trust that my two-year-old girls will be okay?
