Have 9 chicks of mixed breeds 8-9 weeks old. Noticed symptoms (swollen normal color tissue around eye) The eye itself became swollen and bulged. The chick had bloody dirreah overnight and died. The other chicks are now showing the same symptoms around eyes and one seems weak.Until now they have seemed a very healthy flock of chicks. They were hatched by a broody hen. Help! . Anyone know what it is? and how to treat it?
