Dear members of byc, I need urgent help/ advice. Four of my chickens are dead already and rest are suffering one by one. When we found two lethargic and gasping for air, we separated them. One died in few hours and other survived for two days. Then another two had the same symptoms. They died too after two days. We have had them for six months and they were 8 months old. Now others are gasping, moaning, wheezing and seems like crying (sounds). They habe stopped eating too. Yesterday i finally got lincomycin. It said .2 for each chicken weighing 1 kg fpr three days. I injected them all 10 and today too. But there hasnt been any improvement. What do i do? I am feeling bad when i hear them cry. Cant bear it. Please respond to me.
