Safe-guard dewormer for goats dosage for hens

[Henry&Friends]

I have a wheezing, sneezing hen, which I suspect has gapeworm. Today, on my way to work, I spent ~$30 on liquid safeguard 10% dewormer for goats, knowing from this site that its okay to use in chickens. My wheezing hen is separated, in my basement ATM but I am planning on treating the whole flock.

Now that I'm home, I have a few questions. How do I find the correct dosage? should I deworm the whole flock? How would I go about getting the dewormer in the birds? is there an egg withdrawal time? (It says on the bottle not to slaughter goats for 6 days for food, or to give it to lactating goats, and in bold caps that it is NOT FOR HUMAN USE) Is there anything else i should know?

Edit: added pictures and more info

I suspect multiple birds have gapeworm, including the rooster, which is why i want to treat them all. I didnt want to put this in the post to distract from my question, though... This is the first hen with seemingly serious issues, though sometimes I watch the birds raise their head up, open their mouth wide open, then go about their day. She had a liquidy poo this morning and empty crop, i put her down stairs with a bowl of chick starter and water with electrolytes in the dark to rest

This is usually a respiratory problem, not worms. You can treat them for worms anyways if you want. The dose is 0.23 ml per lb of body weight for 5 days in a row. Most use a 2 week egg withdrawal period.

sometimes I watch the birds raise their head up, open their mouth wide open, then go about their day.

They do that to adjust their crop. Nothing to worry about if that is the only problem they have.

She had a liquidy poo this morning and empty crop.

Nothing wrong with that. Sometimes they just leave a runny poo. Maybe it was hot and they drank extra water. An empty crop in the morning is perfect. That means the crop is emptying.

I agree that gapeworm is very rare, and this sounds more like a possible respiratory infection or disease. It will not hurt however to treat for the many types of chickens worms with the dosage that @pibb has privided for 5 days. That would treat gapes as well. It is good to toss any eggs in hens that are getting SafeGuard for 14 days after the last dosage.

Have you added any new chickens in recent weeks or had any respiratory disease before? Chickens tend to get those from a carrier.
