My Speckled Sussex hen is wheezing like she has a cold. I have no experience with this but I think they can get colds. She is acting fine otherwise eating, walking around. I have noticed that the rooster goes after her to chase her off and she is off by herself sometimes. This behavior makes me worry that she really is sick.
Can anyone advise me as to what to do next? Should I isolate her. I wormed all of the chickens with Wazine about 3 weeks ago and am planning to it again in a week.
Any advice would be appreciated.
