Our 30 chicks from the hatchery arrived yesterday (Thursday) morning. They were hatched Monday. One was DOA, a speckled sussex. We immediately fed them GroGel, and offered food (fermented organic chick starter) + water with a splash of ACV. 4-5 of them had pasty butt, which we have been tending to. 5 went to their new home, and another 11 went to a second home, with the remaining chicks staying at our home. About 6 hours after arrival a speckled sussex passed. 2 hours later, another passed (someone from a FB forum said it looked like she had an infected yolk sac). Then, last night about midnight, a wyandotte passed. I found out from the family who took the set of 11 that they had a sussex pass last night, and another is weak. I currently have a partridge cochin about to go, and a faverolle who will only stand, eyes shut, puffed feathers and appears to be shivering even though the brooder is at the right temperature. The family who took the set of 5 have not had any issues. I have not seen an pink or red in their stool. The brooder has heat on one end with a thermometer so I can keep it steady and the food and water at the opposite end with no heat. They have been inside (either the garage or the bathroom). The remaining chicks seem active and healthy right now, but so did all the other chicks yesterday (except the one that was DOA) when they first arrived. I am beside myself and don't know what to do! My little girls are heartbroken and their two favorites (the faverolle and cochin) look like they're not going to make it. Can anyone help me trouble shoot? Faverolle chick. I have separated her and that's why she's in the cardboard box and not the brooder. The temp is 90-95 for her, but she's shivering. This is their poo--the photo makes it look dark red, but I think it's because of the heat lamp. When I wiped it off with a tissue, it was all greenish, no pink or red at all.
