I am thinking of setting up the deep litter method in my coop. I have several questions about it though. My coop is a old milk shed I made into a coop. It has a cement floor. It's measurements are 6 by 8. I have 10 golden buffs. All I've read is that you set the system up in the spring and clean it out 1 or 2 times a year. I have egg layers. I got my chickens in late fall. Didn't have to clean it out for the first month. But had the chickens laying eggs now . I n one week I had a STRONG ammonia smell. So I cleaned it out and put new bedding in. I use pine chips. A full bag in. Am I using to much pine chips . I have 2 heat lamps running. Now that it is winter. I live in Ohio about 1 hour from Columbus. I have 2 windows in the coop I open them for ventilation. How cold a tempature does it have to be before I use the heat lamps or close the windows to keep the chickens warm to prevent frostbite? The 10 chickens that I have are fully feathered. Their is usually a strong wind where I live in the country. The front door to the coop Does Not fit tight and wind does blow in. It does prevent preditors from coming in though. How often should I stir the flooring pine chips? To prevent the ammonia smell. Should I use FOOD GRADE DE to keep the ammonia smell down. Then as I understand it you should put a new cover of pine chips over the DE
