My 6 month old chicken had a terrible respiratory infection and is finishing up her doxycycline over the next several days. We have had her isolated from her pals and the vet wants us to keep her away from them for another month. I'm concerned that this will be very hard on her. We have several acres for them to roam and we're wondering if we might be able to let her roam with her pals during the day, but keep her out of the run and coop at night. Any thoughts? Her symptoms are gone. The vet is concerned that the other chickens might develop a resistance to the meds making it tough to treat them if they ever become sick with respiratory issues. Any feedback? Thank you.
