I bought two hatching's of chicks from two different breeders. One flock of Auracanas that are now about eight weeks old. The second a flock of Marans chicks that are about five weeks old. The Marans get turned out in a run during the day but in at night. I initially lost a few from both flocks from what seemed like a prolonged wasting away that took two or three days befor they died, and then things seemed to level out and everyone was fine. They are fed a medicated starter crumble, the older ones are fully feathered so i just recently removed their heat lamp. Once again I am noticing chicks that have their eyes closed a lot even when they are eating or walking around. They are very lethargic and sleep most of the time. They eat and drink some but it is reduced significantly. Im afraid i will start seeing losses if i don't do something very quickly. Their droppings vary so regularly i cant say if there is a significant change. I see loose droppings sometimes and firm droppings other times. I cant say that ive seen any blood but until now i didnt know i should be looking. No poopy butts though, no nose discharge, no sneezing, no eye bubbles, no crop issues or swollen faces. The run that the younger chicks stay in during the day is on my front lawn and i move it daily. The older chicks are in a three quarter enclosed horse stall on sand. I hope this is enough information to get some help, im really freaking out.
