...our coop smells really strongly of ammonia every morning when I open the shed door. Is there a reason for this? I know I've read here that their poops get bigger, but do they get stronger smelling too? I don't know what to do about it. We faithfully clean our coop every week, I put down DE and zeolite on the coop floor and then we use pine shavings for bedding. It's been three days since we cleaned the coop and they were even out in their tractor most of the afternoon on one of those days (it was raining the other days). We have a little fan on top of the coop that runs as long as the lights are on to help circulate the air. (From 5am until 10pm) I keep them inside longer than I did before, now that they are laying, so they lay their eggs in the nest boxes (can't free range them because I live in a neighborhood and I'm not even supposed to have chickens!) If anyone has any ideas or suggestions, PLEASE let me know...this is horrible!!! P.S. I have to close the shed at night because we have lots of coons and possums, and it's a pretty tight shed...but not air tight. It's one of those metal garden sheds with a coop inside it.
