I am totally new to this site but would love any help you can offer. I have Buff Orpington Chickens. They are sweet lovable chickens. One of my girls, Polly started acting like she was choking. She would extend her neck and open her beak. She isn't making an sounds. Her poop is still normal. Her crown is almost purple instead of bright red like my others. I forced her to have water and noticed that she seemed better after that. I have done tons of reading on here. I'm not sure if she has gape worm. I went to the farm store and bought Safe Guard fenbendazole. I read to buy the liquid for the goats and give 10cc for every 10 lbs. Since Polly is closer to 5-6 lbs. I only gave her .625 cc. She took it quite easily. I will continue this for 2 more days as all the instructions say. How long till I see a difference? I don't want her to die. I'm super concerned. I have had my chickens for over 3 years. Is there anything else that I can do for her? After the medicine she seemed to have a hard time so I feed her some water. Will my other chickens catch it? I have 2 babies that hatched on May 9th and I'm concerned about them. The lady at the store recommended giving Multi-wormer Triple Action (Type B Medicated Feed Concentrate & Vitamin Supplement) to all of them. You mix it into their food. Also, all my chickens share the same coop. What about the eggs we eat? Can they catch it? I could put her separate but chickens are social animals and I think that would be worse on Polly. I just noticed this today but she is gulping every few seconds. I read that they can get this from earthworms. My chickens are free range and do eat bugs and worms. Should I try to lock them up? Any advice is appreciated. Thank you.
