I have a bit of a problem here with coccidiosis and capillaria worms (hairworms). I have 8 pullets and cockerels (started out with 14, lost 6 over the past month), and I have 4 adult birds, all housed together. I submitted two dead birds for necropsy and got this diagnosis. I've been treating all of the birds for coccidia, with amprol, and my plan is/was to start de-worming next week. It's very hard to get advise here locally. My dog's vet doesn't deal with poultry, and the local poultry consultants, who I have spoken with, deal with large commercial scale operations and are quite liberal with advise about drugs, and I find I have to filter their advise. There is a pharmacy here locally that deals with animal products, both medication and natural, but they are reluctant to advise on the drug issues for animals. They want you to do your own research, and they're give the nod of approval when you settle on a treatment. I haven't done any de-worming before. I started this flock after losing my previous flock to a dog attack. I had been using DE as preventative, and keep the coop and water/feed clean. I started out with the four adult birds, which I bought from a very reputable breeder. It's a very clean operation. However, I should have de-wormed them when I received them, as she had advised me to do. I didn't do that. Then I bought the 14 chicks from her, and because they had no mom and the weather was terrible here (cold, wet spring and early summer) they were inside for the first few weeks. I understand now that set them up for coccidiosis, as they didn't develop a natural immunity, doing what chicks with a mom normally do. Anyway, the 8 remaining chicks have not been sick, but were a bit less active, and are responding very well now. They've really come around again. In addition to treating hem with amprol, I've been giving them all a mash of buttermilk/yogurt, garlic, pumpkin seed powder, Vit A. But, I thought I should get on the de-worming and the poultry vet advised to do that 24-48 hours after the cocci treatment is finished so that will be next week. But, I understand it is not advisable to de-worm chickens until they're about 5 or 5 or 6 months. Does anyone have any literature around that, or can anyone advise on that? I have read that fenbendazole is the de-wormer indicated for capillaria, and I understand capillaria (hairworm) can be hard to get rid of. I can get the fenbendazole at the pharmacy, but again, they can't give me advise about dosing. Does anyone know about the dosing? I had read that you can do a 1 or 3 day treatment. But the poultry consultant said to do it for a week, and repeat after 19 days. That worries me, in light of what I've read about de-worming being hard on chicks, and the concern about treating young chicks. Here's what I read at http://msucares.com/poultry/diseases/solutions.html: One-day Treatment 1 oz Safeguard or Panacur per 15-20 lb feed Dissolve the fenbendazole product in one cup of water. Mix this solution well into the feed and give to the birds as their only feed source for one day. When completely consumed, untreated feed can be given. Be sure that the commercial medication contains 10% fenbendazole. Safeguard is a product of Ralston Purina, and Panacur is a product marketed by American Hoechst. One ounce of medication will treat about 1000 10-oz bobwhite quail. Adjustments of the amounts of medication and feed needed may be necessary depending on the number and size of the birds. Three-Day Treatment 1.2 oz Safeguard or Panacur in 100 lb feed -or- 4 oz pkt of "Worm-A-Rest Litter Pack" (Ralston Purina) in 50 lb feed -or- 5 lb bag of "Worm-A-Rest Mix Pack" in 495 lb feed Feed all the medicated feeds free-choice for three consecutive days. The feed mixtures provide 75 ppm fenbendazole. Quail will receive about 1.7 mg/bird each day for adult birds or 2.75 mg/lb of bodyweight. Fenbendazole has been shown to be a very effective treatment for eliminating Capillaria (capillary worms), Heterakis (cecal worms), Ascaridia (roundworms), and Syngamus spp. (gapeworms). Toxicity from overdosing with fenbendazole is very remote. Research indicates that amounts up to 100 times the recommended dosages have been given under research conditions without adverse effects to the birds. Use of this product during molt, however, may cause deformity of the emerging feathers. [end of quote] Does anyone have any experience with this, and can you tell me what dosage and protocol I should follow? And can you tell me if I should treat the younger birds, as well as the 4 older ones? I do have to treat the four older ones, though two are broody. That's an added complication. Eggs are due to hatch on the 19th. The rooster seems healthy but perhaps a bit less active though I figured he was bored, as two of his ladies are on the nest brooding, and the 3rd hen hasn't been well. I've now concluded that she must have worms. She's been sleepy. She eats, drinks, roosts, walks, runs, but constantly sits and closes her eyes. I had been treating her for an abscess on her bottom, which is improving, and thought it was because of that. Now that I know I have a worm issue (and adults aren't likely to be susceptible to coccidia, I understand), I wonder if her sleepiness is due to worms. I've been hand feeding her the mash, and I do think she's picking up a bit. So, lots going on here. I'm not happy, but have to sort it all out, and quickly, so the next hatch has a better start than my beautiful lavender orpingtons and wheaten marans have had. Thankfully, they're looking good now.
