Ok, I did contact the state vet and they referred me to my regional person. I talked to him for a while explaining all that had happened and he said based on the symptoms, it is not one of the two things they monitor for. He suggested using either Baytril 10% oral solution, Baycox 5% oral solution or Tylan Soluble (all mixing in drinking water). He emailed me the info to take to the vet with me. I liked this vet much more than the other one. He examined my hen real well and found that she has lice and also 2 kinds of worms (whip worms and another kind of stomach worm that he wasn't sure of). He gave her an antibiotic shot of Baytril and gave me some to bring home. He prescribed Ivermectin for the worms and wormed her and then we wormed all the other chickens except the chicks (we assumed they are too young?). Now the Ivermectin is mixed 50/50 with something else but I don't remember what it is and it's not on the bottle. He also gave me Permethrin 10% to mix with water to spray my chickens, the coop and any free range areas they go in but also told me to keep any animals out of the area for 24 hours because it could/would kill my cats.I have 7 outdoor cats and 2 of those hang out around the chickens and their coop most of the time. Spraying the chickens sound like it would be hard not to get it in their eyes or mouth and a lot of work. I have read on here about using other things for lice. Wondering about using Epernix Pour because it sounds very easy to just put drops on them or using the sevin dust, but not sure how much to use of course I can research that. I have a large outside area they free range and wondering best way to treat it and also not kill or harm my cats. I would also like to note that I have 5 mallards (just over 4 months old now) who also free range with the chickens and roost in their own house next door to the chickens. The vet said I probably need to treat them too. Now this could get tricky as they do come near me when I'm out there feeding, watering, cleaning but they would freak out if I tried to catch them when they are in their house and they have very sharp claws (learned this last time I tried to pick on up and hold it). Do I treat all the chickens and ducks for lice - even the youngest chicks that are about 1 1/2 months old or what?
Wow, that is an unusual vet! Nice- but wow!
Sorry I am not caught up-but are your hens better?
