I have a sick little chicken and a fecal sample showed positive for ascaridia and caplillaria worms and coccidia. The local stores don't sell medicine for coccidia but did have a liquid wormer, Neobicide. I bought some neobicide locally but the people in the store gave conflicting information about how to administer the medicine. One said to give it by mouth for 7 days, the other said to just give it one time. So I came home to research it and found a website that said it was to be applied externally. Now I am really confused. Can you tell me for certain how Neobicide is to be administered properly? I don't want to poison my little pullet, she is sick enough already. I found this page https://www.backyardchickens.com/a/coccidiosis-how-to-treat-it on how to treat coccidia and have ordered some Corvid liquid from Amazon, that should be here Tuesday. I'm also thinking that if one has worms maybe the whole flock has worms and I should treat all of them. It was suggested by someone on another forum that worms could possibly be the reason my little cream legbar pullet went lame mysteriously. That is what started all this. She told me where to send the fecal sample and I got the results yesterday. While trying to research the proper dose for Neobicide (read lots of places that say it is a good wormer, no one really says how to administer it) I read also that worms can cause problems with their crop also and now I am wondering if we might have been able to save my little black copper marans in November, maybe she had worms too and could have been treated. I'm really not happy with veterinarians right now, all they ever tell me is "you should kill your pet." She didn't even try to save my little pullet. She sure charged me $100 for walking into the office though! So I'm trying on my own to save this one. Please - if your advice is "cull" then don't respond. Maybe I'm crazy for trying to save a life but I'm trying anyway. So I have the 1 oz. dropper bottle of liquid Neobicide. (It does not say what the active ingredient is on the bottle. Nor does it have administration instructions on the bottle.) I thought it was internal (like I could put it on some bread). It says: Recommended dose: 1/4 ml. per 5 lbs. of body weight or 7-10 drops. Indications: For effective treatment and control of gastrointestinal worms in gamefowl. Some websites say it is also effective for delousing and mites. They describe applying the drops to the back of the neck of the bird. Thanks in advance for your help.
