It sounds like cocci wiped out your little flock. Sorry for your losses. It might be too late to save your last chick, but you can purchase Corid 9.6% liquid solution and give it to him. Dosage is 9.5cc's per gallon of water. Give it to him orally using an eyedropper often during the day and hopefully he'll make it.
