for the last 2 weeks i have a hen that has been showing signs of some kind of sickness, first i noticed she really cant move and when she does, its more of a wobble, seems as though her equilibrium is off balance, she is eating and drinking regular, but i have to give her food in her area where she will not move at all until she lays an egg, one everyday. i have checked her out and there isn't any mucus or fluids on any part of her body. someone said it could be a bird flu which is very dangerous. anyone have any suggestions, are the eggs that she is laying OK to eat? also Ive been feeding them a laying pellet blend.
