Let me quickly give you what is going on. They collected 50 birds to rearvandbout of the 50 birds more than half of the birds are dead. Without any calculations that is a total loss on the production which has already affected the capital used in the production of the birds. They are already frustrated and depressed with the way things are and even to take care of the remaining birds is very tiring and day by day they are feeling not concerned again.
I observe the birds and noticed some are malnourished and folding as if they are feeling cold. Some are big and while some are small in size. It could be the vaccine that they use for them failed in the procees of giving them which is either Lasota or Gobborro. And also they should always make sure the birds environment is dirty which at a time they have chicken pox though non of them have it again but the chicken pox can make the chicken not to eat and make them lean.
Since the birds are big they should sell them off and do thorough fumigation inside the poultry so that it will not affect the next production.
