Dewormer for molting chickens

[Tgmcr]

Some of my flock is showing symptoms of what I think may be gapeworm. I have never dealt with it though so I’m not 100% sure. I was thinking of deworming and also using an avian antibiotic I found online I case it is a respiratory issue. Would it be safe to give both a dewormer and an antibiotic to them?
Also, what would be the best dewormer to use? It sounds like fenbendazole is pretty common, however some of the chickens are molting and I read that you shouldn’t give it to molting chickens.
Any other dewormer suggestions?
Thank you!

Looking quickly at your other threads, you've had some losses. Were you able to get some testing to find out what happened?

Are you in the US?

Please post a video of the birds and their actions. For video, upload to youtube and provide a link.
If video is not possible, then please post some photos of the birds and their poop.

You mention an "avian antibiotic", what is it? Do you have a photo of the product please?

Fenbendazole is a good dewormer, but shouldn't be given to molting birds since it can affect feather growth.

Valbazen (Albendazole) can be used to deworm the chickens. Dose is 0.08ml per pound of weight given orally once, then repeated in 10 days.

Gapeworm is pretty rare and it would be uncommon for a whole flock to be symptomatic from Gapeworm at the same time.
Likely you are dealing with respiratory illness, but hard to know. Detailing symptoms that you see would be helpful.
