About a month ago, I had an adult goose die. She just got lethargic and one morning I found her dead. My pygmy goat had attacked her a couple of days before so I thought maybe it was because of that. Then some of my chickens started acting sick, then a turkey, then my other goose. They get pale and thin, quit trying to eat and die. I tried Wazine, thinking the thin and pale was from worms. No improvement. Read up a bit more and found the list of cocci symptoms, which matched perfectly. They've been on Corid for 2 days now. The sick ones that didnt die before the Corid have shown no improvement. There are some others that are showing the thinness, but not pale yet. I dont know how long it takes to be sure if the Corid is doing anything or how long it'd take for them to start gaining weight, if there is any improvement. *The chickens that have died are 2-3 months old. *The geese and turkey were/are over a year old. *Only my free range birds have gotten it. I have 1 month old chicks in a raised pen and 2 month old turkeys in a run on the ground (the other birds can come right up to the run), none of these have shown signs. *The only bird species that hasnt shown signs at all are my ducks. *Excrement is runny on sick birds. It is green, but they free range so I cant really diagnose based on color. *Some of the sick birds have some poultry lice. I dont know if this is cause or just the result of reduced grooming due to sickness. Want to dust, but not sure if I should when they are sick. *The sick birds look unkempt. Feathers are not smoothed out like they should be. *The sick birds stumble and have a hard time standing up. Not sure if a symptom or the result of them not eating due to sickness. *The birds have access to grit and oyster shell. *They free range and receive pellets/crumbles. *I always get my food from the same place and used the same brand for the last three years. *This is the first time in 3 years that I've had any sicknesses. Any thoughts or advice would be great please.
