Not sure when chickens molt,,,seen some rough looking chickens at a neighbors house...not sure what the deal was...mite,rooster or molting...still to much of a newbie...Never got this far last year...Mine got whack by coons in mid July...8 and 1 died a day later.Now I have 15 well fed and fat hens that are doing great!!! Getting 13 to 14 eggs a day.Yesterday went 15 for 15!!!!! So Iknow I have no slackers in the group!!! Winter is going to be interesting!!!! I have bushes to keep the north winds down,,,high trees to the west...Coop faces east....high ventilation,,door to get in and out..West has a 18 inch wire opening at the top,,,going tocut that to a smaller opening for winter...What kind of water heater and is it in the coop or outside????? Rather it be outside,,,cut down on the 'girls" making a mess inside.Straw inside on floor ,,pine shavings in laying boxes.Remarks???? Thanks ,,,,Kevin
