Hi all, I have some spitzhauben chicks that are 5 weeks old and a couple have gotten sick and died. they just stop eating and drinking. They look sleepy and no energy. I was using pine shavings, but lost one chick, so I switched to sand (bagged play-sand from Home Depot) They seemed to be doing better, but I just lost another chick today and now another one is not looking good. I am feeding them Dunmore medicated chick feed, grit, occasional watermelon, oranges and zucchini. I've also given them save-a-chick electro lights and probiotics in their water. I did try to hand feed them water with a dropper, but they seemed like they could not swallow well and gapped ? Any ideas? Please help me save my babies.
