Howdy, neighbor! I'm in Nevada County, too. My chickens have air conditioning in their coop - haha! Misters are good, too, but my flock doesn't like them because of the noise they make. Your mileage may vary.I’m in a brand new member in southern Nevada county. I’m on a skosh under 10 acres of raw land (with well) and am wanting to keep some poultry. Starting with chickens, but ducks will also happen.
I’m thinking four egg layers to start with, kept in a mobile coop/tractor until Autumn rains. They’d be sharing a 3000+ sq. ft. run with a couple LGD pups that were raised with goats and poultry, and would be somewhat mobile, as the run is electrified poultry netting that I plan on moving from time to time.
Anyway, I’m here to get better educated on the ins and outs of chickens in Jefferson er, NorCal.
I have a similar setup, minus the LGD. Electric poultry netting = awesome. I have 19 chickens and 5 ducks.
As for heat tolerant, I recommend Naked Necks or Leghorns. If it's eggs your after, Leghorns all the way. But I find my chickens tolerate heat ok with a covered run, deep shade, lots of fresh water, and cool treats like refrigerated watermelon. Fans and misters are good, too. The air conditioning is just a bonus! I have 16 different breeds, and they all manage. My Welsummer and Spitzhauben do the poorest in high heat. My Naked Neck, Leghorns, and Plymouth Rock do best.
