ok, i had put a baby cow in my coop for a few days when it got really really cold. when it died on me (*way too long a story, dont buy from animal brokers) i dug out where it had peed and put in fresh dirt. I still have an ammonia smell, and because the coop is closed in, it still smells like ammonia. i dont have a place to get sweet lime. do you think i can use some arm & hammer baking soda on the ground and then put a layer of hay above it? I have some wheezy chickens and i'm pretty sure it's from the smell. I have them on antibiotics just in case.
