I have a lethargic Blue D'uccle Chick that has been worrying me. I've seen he/she eat and drink but seems to sleep quite often and definitely isn't as playful as the others. I haven't noticed any strange droppings, although I don't recall seeing any droppings from this particular chick at all. I've checked for "pasty butt," seems to be fine in that area. I've had a chick die before, so I'm not sure if I'm just paranoid or if I should be worried. Can't afford to take him to the vet. How would I know if it's cocci? Should I get Corid?
