Where is the odor coming from? If the poultry area is maintained on a regular basis, there should not be too much of an odor. I know sometimes when it rains my runs give off an odor, but other than that I do not notice too much. Lime can be used to get rid of odor, but you have to be careful not to breath it in. Works well, but I try to avoid using it. I also recommend roto tilling the chicken yard if that is the source of the stink. Other wise, a good overall cleaning of the chicken house should do it! Lay down some nice fresh shavings and that usually does the trick.
Is it your composting pile? Thurs nite I cleaned the entire deep bedding, piled it in a hole that I wondered how the heck the hole got there in the middle of the winter's compost. Fri morning went to turn on the lights to wake up the girls. Rounded the corner of the house and there was the odor and I'm thinkin' HOW could it smell so strong already??? I just cleaned last night!!! It was the composting pile which sits on top 6 feet of snow and it was STEAMING!?! Made me realize just how hot that stuff was and scared me about burning up my hens in the coop or instantaneous combustion this summer!?! Of course I knew I'd be cleaning more often in warmer weather along w/the birds able to free range within fenced areas but you should have seen the steam coming off that pile in the snow, that's exactly how the hole was created- bet there's another hole today...if only we could run vehicles off chicken poop, what POWER, we could go to the moon
