I posted yesterday that I had about 5 out of my 10 adult hens who have come down with an acute respiratory disease. Upon further reading I believe that it is ILT - the description sounds just like it and they have been coughing up a little bit of bloody mucous looking stuff. I tried treating with tylan 200 yesterday and they actually seemed a little more stable this morning - but if it IS ILT then its a virus and not treatable, but hopefully they won't die from secondary infection. ANYWAYS I also recently received some chicks that are separate and in my house. I have been changing clothing and washing before working with them, but am afraid of transmission. Where can i purchase an emergency vaccine for my chicks???? I would love it if someone could send me a link. Will it work? Or is it too late??
