The little chick I posted about previously seemed to recover, and was even running around happily for a few days, eating, etc and then she relapsed and died. The second time, giving her electrolytes did not help at all. She was struggling to breathe at the end, and maybe had a small amount of mucous around her beak. The chicks must be about 7 weeks old now.
Now, another chick in the group is sitting huddled with her eyes closed and mouth breathing intermittently. They all looked completely healthy last night. I read a lot of posts here about gapeworm, and I did open this chicks mouth and look in, but couldn't see anything that looked like a worm. So I am not sure if I should assume respiratory, or assume gapeworm. I can get some meds from Tractor Supply. My son was so upset about his little chick dying last night, I'd like to try to save this one - so - should I try to treat for respiratory, or gapeworm, or both?
