Where are you located in the world?
Gapeworm is fairly rare in poultry. Respiratory disease is often the cause of a bird's gasping.
To answer your question - Yes. Fenbendazole will treat Gapeworm. Dose is 0.23ml per pound of weight given orally once a day for 5 days in a row.
Hi Wyorp Rock
I'm 99% sure my chicken has gapeworm - no other signs you mentioned for respiratory issues or swollen anywhere.
She was gaping and shaking her head a few days back with an occasional odd sound - like a sneeze/cough/choke combination. Now she's been gaping for 3 days solid. It's aweful to watch. She can't eat or drink and hasn't for at least 3 days. Last night she was still walking slowly but the fight has gone out of her.
I'm in rural Queensland, Australia and only found kilverm and avitrol tablets in the shops.
Avitrol tablets say it's not for dosing food producing animals.
Kilverm isn't prescribed for gapeworm. I called the manufacturers and they told me that their levamisol @ 14g/l isn't the same quantity as products prescribed for gapeworm.
Not knowing what else to do - and getting the "legally we can't tell you" on the phone from vets and labs and the Avian University in Brisbane.
I gave her 5ml by syringe 2 weeks ago. Slight improvement
A week later she was in distress again - another 5ml by syringe. Slight improvement for 4 days.
Then she got bad fast.
I've given her 5ml by syringe 3 days in a row with zero improvement.
She's not able to eat - I found a recipe online to feed her (water, banana, few grains of salt, molasses -i added hemp seeds - blended it up in a 250ml concoction) I gave that to her by syringe - 10ml an hour apart 3 times yesterday afternoon. Planning on giving her 10ml every hour throughout today (if she's still alive this morning)
Question - if she's still alive this morning - what do I do?
I doubt I'll get a tablet down her - I couldn't even get grain or a piece of a pellet into her.
I'm considering 6 avitrol tablets crushed and mixed into water? She was almost 5kg but she's wasted away so much I'm guessing she's down to 3kg.
No doubt I'm overdosing her but at this stage she's clearly in such distress I can't believe she's still holding on.
