Baby chicks that are shipped are always at an added risk of delivery stress--handling at packing, delay in the shipping, rough handling at shipping, and possible significant temperature changes.
Just a guess is that these chicks needed feed and water some hours earlier than they reached you. Only the most robust or latest hatched chicks can go without food or water for more than the suggested 36 hours after hatch.("Stromberg Better Guide to Hatching") It is not usually possible to stretch that time before needing food and water, except for strongest chicks. Doubt they have disease, are just what can be called "fading" chicks. If the losses begin only after 6 or 7i days, lack of vit A,D can cause the fading and death. A drop of plain cod liver oil can save such chicks. Placed with an eyedropper under the top beak, allows the chick to swallow it without choking. If this can be a cause, A day apart--3 times in all, can do the "save". Might be worth a try for your survivors? So sad to lose any chick. Have you notified the Hatchery or person who shipped your chicks? Good luck, CJR
