Hello all. We ordered a batch of 25 chicks from Sandhill Preservation and got them shipped to us Thursday morning. They sent us 28. Two died during shipping, and since then 3 more have died as well. I'm not sure where we are going wrong, or if we can do something else to save them. Here's the story. Our brooder is a large cardboard box with sand as a substrate. We noticed a couple of the chicks we're pretty lethargic, and they both had one eye crusted shut. Since then we have separated the ones who seemed sick from the rest of the flock, and mixed their water with duramycin-10. Since then, both of their eyes have opened and they seem to be doing better, pecking at sand, eating food, and doing general chicken activity. The problem we are having is every morning we have woken up to check on them, one of the chicks that seems perfectly healthy has died, and we have no idea why. They are of the same coloration, so I wonder if it was a bad hatch for that particular breed? I am out of answers. Our brooder is at 90 degrees, they have plenty of fresh water and food and heat, and we have been keeping their litter and their pasty butts clean. Can somebody help me out? I'm not really sure what other info is needed. Should we give the entire flock antibiotics just to be safe? I'd really rather not medicate the whole flock, but I'm really nervous about the random dying. Help?
