Hello, we kept two undersized cross bread meat birds that are now 4 1/2 mon. old. The hen has had an ongoing problem with rank, stinking runny lite brown poop for which I just treated with sulmet for 5 days. It has been wet and cold here in southern Oregon kinda suddenly and last week she began to sneeze a little. Today she is sneezing a lot more and in addition is making a shrill whisling type of noise. I have a cross breed rooster that besides being a glutonus pig shows no sign of illness. I am worried about the two buff orpintons we just put in with them last week getting the same thing but as of now they do not show any signes of sickness other than one poops an odd runny, jet black poop and does not lay eggs. Any ideas, I keep looking in the forum but can't seem to find a definate answer. thanks for your interest BR or bust ps -- I rigged up a heat lamp for the coop and set it up on a timer from 10 pm to 7 am.
