Hi Patti, I'm also in Michigan, west side. I've never been around chickens - this was ALL new to me. Chicken's home consisted of 5ft chain-link dog kennel (chain-link top, too), a place to roost was a closet bar and vertical, 1 shelf, bookcase. The inside of kennel lined w/ straw stacks, & tarp covered outside. Didn't know kind of chickens we had. One day came home to close coop as weather took a turn for worse & found our chickens right outside coop drenched from rain w/ wind-whipped feathers. Felt like worst chicken owner in world to let that happen (coop door flung shut...they were unable to get in)) Was certain they would die as chickens don't do well w/wind/rain. They survived just fine. Oh, they did not have a heater in coop, nor heated water (the pilgrims did not use all those things, so...) I gave them a cereal bowl of water in morning & night. Treats daily -plain yogurt, blueberries, scrambled eggs, and/or mealworms. NO medicated feed. Once in awhile, small amount of apple cider vinegar to water. Come winter, I put a battery operated small lantern w/them at night, but battery would die out an hour later due to cold. After having worked a 16hr shift, came home one night, the coldest night of the year at -30 degrees with wind-chill, certain they were dead, I peeled away the tarp, opened up the gate, and using flashlight, checked in on them. What I saw next was jaw-dropping....there, on the book shelf, where our hen Amelia would sit, was her first egg. Wow! She laid 5-6 eggs every week since! Green eggs. She was an Easter-egger & the sweetest girl ever. So, Easter-eggers are definitely Michigan cold hardy - as well as several other breeds I've since purchased: Buff Orpingtons, Wyandottes, Australorps, Barred Rock, and Light Brahmas. I do have a Show-Girl Silkie hen who did fine this past (first) winter. I was concerned because she does not have that water-resistant feathering like other chickens, and has NO feathers on her neck. At night-time, she just camps out in a nesting box :) .
