I am hoping that someone can help me with this. I have lost 4 chickens in the last month. The last two have a puss like brownish puddle under their beak when I picked them up. One of the them that passed last did seem to be a bit stand offish and didnt eat for a whole day before this. the first two that passed just seemed to lay in the run for a day or two before this and then they both passed at the same time. Its strange because it has been two at a time and all hens or pullets I should say they are just 16 weeks now. Symptoms are lethargy not eating and this last one seemd to have a discharge ? when i had noticed a bloody stool in some of the birds I began to use Sulmet in their drinking water afraid it was Cocci.
