I found this thread searching for gapeworm, because one of my 22-week old pullets - one that laid first, often and with several double-yolk eggs - is breathing through her mouth on the roost, shakes her head, sometimes rests with eyes closed when everyone else is active in the enclosure. But, she is eating and does forage still. But she seems weak. Some people worm regularly, just assuming worms, but my neighbors have had chickens for years and no one around here worms or seems to have problem. I am not inclined to regular worming unless it is absolutely necessary. I swabbed, but was nervous to go to deep in her throat. I didn't find worms, but I think I would need to get deeper in her trachea (?). I've read that people often misdiagnose respiratory disease as gapeworm. Is there a way to tell without a vet? I suppose to give safegaurd and see if it fixes her. But, if it is respiratory or something else, wouldn't that just stress her? I know many would simply cull, and if I thought she could not fully recover, that might be the thing to do if she continues to decline. Thoughts?
