Hi there, I have two young chicks, my guess the oldest is about 3 to 4 months and the other one is probably 8 to 10 weeks. Both have become very lethargic sleeping and laying down most of the day with their eyes closed. I have brought them inside because at first I thought it the heat in the Florida summer... they're still eating and drinking, but have not improved. Their droppings are also normal... even though their eyes are shot there is no swelling or discharge of any kind, I've already added can electrolytes to their water and poultry cell to their food... any other advice?
