Dosage help?

[Mandykay]

So I have a hen that has had a recurring sour crop. I have had x-rays done and everything looks normal, no obvious blockages, tumors etc. I have treated with monistat and nystatin. It gets better then comes roaring back. I discussed with my vet trying fluconazole and she agreed but they didn't have it in office so I ordered it from chewy and my vet approved the script. So now I am getting it, but need dosage help.

(Fluconazole Compounded Oral Liquid Chicken Flavored for Dogs & Cats, 25-mg/mL) this is what I have coming, my girl weighs 3.7lbs. Can anyone guide me in the proper dosage and rate? I will discuss it with my vet but want to have place to start as she is not a poultry specialist, but an amazing farm vet that has graciously agreed to treat my pet Chickens.

Dosage varies between each link I have read, from 5 mg to 10 mg per kilogram (each 2.2 pounds) given once or twice a day. Here are some threads to read about dosage:
