4 yr old peahen is opening her mouth as if she is gasping for air or attempting to make a sound. I don't see any other symptoms. She was wormed a couple months ago, don't had the date but before mating season began. Any thoughts or suggestion. The peacock seems healthy no other guineas or chickens I have appear ill. On hand I have tylan 50, safeguard, and sulmet, possibly other but that is all I can think of at the moment. The farm store is only about a 20 min drive. Any recommendations? I plan on taking her off her roost tonight to check her over, but don't want to chase her around & stress her while attempting to catch her now.
