Just to introduce myself...I'm a single retiree living in Central Oregon. "Back in the day" I used to have chickens and am now thinking to get back into the swing of things once again. But at my age I'll have to do this on a very small scale that's for sure. I think I'll have 4 chickens, no rooster (yet!) and see how it goes. Here in Central Oregon we have extreme temperature swings...could be +75 during the day and plummet to +25-30 at night during the summer months. During the winter months we are literally in a deep freeze. The months of Dec/Jan/Feb can see the temps fall to -20 at night, so I am concerned about their well being. I think that with such a small flock and coop I could keep them safe and healthy with a simple light-bulb system. If anyone has any thoughts they'd be most appreciated...thanks!
