I have 14 chicks around 6 weeks old. They started with runny noses and sneezing now they have bloody stools. I'm curious if it is possible for a respiratory infection to cause bloody stools or did coccidiosis cause the respiratory issues. All chicks are now receiving tylan 50 injections and corid to hopefully fix the problem. Amy advice would be great. I have lost 2 chicks since yesterday. Just to clarify runny nose started Sunday bloody stools started Monday night. Thanks in advance. It is Wednesday today.
