I just recently purchased some chicks from someone. I have learned my lesson now. I thought I was safe because they were NPIP certified. The chicks were really sleepy and had bloody stools. Now ALL of my chickens have it. The ones that were old enough I treated with Tylan 50, I have Sulmet water in all of the younger ones water. I have been feeding boiled eggs and adding electrolytes as well. O also gave them some milk as I was told that milk would stop the bloody stools. I lost 1 of my show quality silkies so far and several others look bad...is there anything else I can do? I have thousands of dollars of chicks at stake here...not to mention I love each and every one of them!
