Sorry for your loss, Maggie P. I have nine 8 week old Buff Orps chicks that are outside in a separate chicken run - the older hens and the roosters can see them, I have not had problems with Mareks before, but the other day I noticed that 3/4ths of them have blue eyes - on both sides. They are still in the house with their mothers who are about 1-1/2 years old and are acting normal. I had never looked into their little chick eyes before: they are eating and drinking and lively so far, their pupils are not misshapen. I am worried sick. I will watch and wait for those crucial weeks which have begun to see what happens. The rest of the flock (7 hens and 2 roosters and 2 ducks seem OK for now. All are at least 6 months old. Is there something else I should do?
