Hello, I have a 6 year old barred rock hen, about 5-6 lbs, who is sick. I have been reading all the wonderful information available on this site, and it convinced me to join. Dharma moves her throat (trachea) and crop back and forth like she has something stuck. She doesn't gape. She sounds gurgly when she breathes. She stopped eating and drinking about three days ago. She will accept a few bites of favorite foods fed by hand, but then she stops and shakes her head and clicks her beak. I saw from many posts that people use Safeguard (fenbendazole) for treating gapeworm. I have seen that people suggest using a pea size drop. Can someone who has done this please verify for me that what I have is the same as what you have used, and that a pea size drop is safe and effective? I have: Safeguard (Fenbendazole) Equine Dewormer 25 gram Paste 10% (100 mg/g) It sounds like people have had success either putting it on a piece of bread. Does the paste dissolve in water? And for how many days do I do this? Does it need to be repeated after a waiting interval? Thank you so much to anyone who replies.
