Hi every one! I seem to be having an ammonia issue in my smaller coop.... it houses 14 chickens and is about 15feet by 15 feet. I have ample roosts and plenty of nesting boxes.....here is my problem We were hit really bad with Hurricane Irene, in fact the coops were under about 12 inches of water..... the poor chickies were stuck on thier roosts for days....well ever since then some of them have taken to sleeping in the nesting boxes. I have a sand that covers a metal floor. Since the hurricane the coop has been totally cleaned out and sanitized, and new sand placed in the coop area. It has been raining here for the past week and yesterday I noticed the coop smells horribly of ammonia and I can not find the spot where it is comming from. The sand is clean, the food area is clean and I clean out the nesting boxes they sleep in every day. There are no leaks from the outside. The boxes are filled with shavings.. I am thinking there is a nest box I am missing.... what do you guys think???
