Checkin' in from Southeast Texas. I have three Rhode Island Reds, and with the recent rains, the pen got muddy. Duh! Well, now I detect an ordor that is not pleasant. Duh! again Anyone know what I can do to eliminate this? Is it safe to spread lime in the chicken pen? I don't want my neighbors getting this aroma. Thanks all for your help. Glad to be with Backyard Chickens.
