Anyone have this experience? They are outdoors during the day, but indoors at night due to a predator threat (even though they have a secure pen on the patio with double hardware mesh all round and a padlock). This is driving me crazy worrying about the smell and their health. They are a trio of one Jumbo Pekin, 2 Golden Hybrid 300 layers, and a small Black Swede (he lives in a separate pen). The Jumbo may have asper, the others are OK. The Jumbo is now upstairs and is on meds. He drills in moist soil and may have picked up something with the weather change. Sheer hell living with this worry, and the constant predator threat. HELP.
