Hi, we have had 28 chicks hatching and all healthy for 2 days. On the third day 15 died and many more. The symptoms are that they stop moving, act lethargic, it also looks like their neck is broken and goes all floppy. After that they close their eyes and curl up. They stop eating, drinking and even had to force feeding natural yoghurt with chick powder. They won't swallow and basically give upon life. They then start gasping and shaking and die in my hands...it's so upsetting for them to die even though we have tried everything. We gave theo extra heat, electrolytes in their water even giving them molasses. Is it a disease? Could it be genetic? The mother quails also live with their brother and have seen him mating but we know separated him to a different coop. Could it be bacteria? Could someone please tell me?!?! We only have 11 healthy, active ones left.
