I have 25 broilers that are almost 6 weeks old. I had one die last week, I believe from "flip" syndrome. Found it on its back in the morning. Now I have one that is not moving/eating or drinking. It opens its mouth and breathes hard. Its eyes are closed and feathers ruffled. Both of these chicks were always much smaller than the others, kind of like runts. I was planning on culling the sick looking one tonight, but not sure if it will be safe to eat? It doesn't have watery eyes, fluid or snot around its face. Has anyone seen this before? Is it safe to eat? All the other birds seem healthy.
