Hello, I got 8 chickens (full grown and already laying) about 4 months ago. I don't know what breeds they are but can describe them: 2 are black and white speckled with red combs, 2 are big and blond, and 4 are smaller, brownish/red (they remind me of pheasants without the ring-neck or long tail) and they have long curls on their cheeks. Anyway, we built a coop (it's about 8'x10'), ventilated, with a run, man door on the side remains closed unless I'm gathering eggs or cleaning it out. We use pine shavings for the bedding. There are perches. The pen is 12'x20', completely enclosed (I have hawks in my yard). I should probably also tell you I live in Pennsylvania. OK, so the girls adjusted well, they eat a layered mash/crumbles I get from the feed mill and I keep their water fresh. I was told apple cider vinegar in the water can help with parasites so I put a little in there everytime I fill it. I was getting about 4-7 eggs per day during the summer. Lately (the past 30 days) I get 1 egg per day. I used to get blue/grey eggs, but whichever chickens were laying those quit - I get brown only now. I read that the change in season/lack of sunlight might slow egg production. Also that molting contributes. I have put a light in the coop, just a regular, 100 watt bulb in one corner with a timer set from 5am-8am then from about 4:30pm-8:30pm. This has only been in place for 48 hours. Will this work? Should I see better egg production if the molting ends and the light is in place? Should I keep the light on throughout the day for warmth? I have some Amish farmers as friends, but they don't use light or anything in their coops. They also don't seem to mind when one of their 80 or 90 chickens dies, whereas I am more concerned about my 8. Am I on the right track for the winter months and will I get more than 1 egg a day? Will they be cold without a light on (I imagine it couldn't be good to leave on all day and all night) or will I need more hens for body warmth in a coop that size? Thanks for any help you can give a newbie!
