we have a free roaming flock around our farm, last week while hubby was at work someone dumped 2 dogs that basically masacred our flock (+30) I was out of town and hubby has been up to his ears in work so he came and shot the dogs, after a few days a few chickens, ducks and 2 turkeys started foaming at the mouth, he gathered them up and put them in the chicken house , half of them died half lived but we would like to know why a week later 3 more are doing it, the simptoms are.. Foaming, acting all crazy and legs buggered, some ided about 2 hrs after showing simptoms, the ones that survided look great? The ages range between 2 months old to 14 months. Have anyone have something like that happening any advise? thanks
