We bought a young hen/roo (not sure which) in April as a three month old. He stunted, literally only growing about 4 inches and is not growing anymore. He is a Purebred Orpington, but isn't much bigger than a bantam in size. He has been sneezing a little bit lately. His breeder sent off a few of her dead birds she thought were doing something out of the ordinary and got the horrible news that they were infected with Mycoplasma. She has a huge flock of many different purebreds and has to terminate them all. I know she is heartbroken because she just lost her entire Lavendar Orpington flock a month ago, and now this. She says that anyone who bought from her prior to this shouldn't be worried, but I don't know much about it. I know our only two laying hens have started laying crazily, randomly throughout the week. One is a sex-link hen of 1 1/2 years and the other is a pure Orpington of 2 years. For the past 4 weeks neither has layed normally. We haven't had a change in feed at all, and they are in the shade all day and free range. The only change is we added a new mom hen and 5 babies to our flock, but that hasn't noticeably bothered them. The only symptoms I can find are sneezing, coughing, watery eyes and dirty nostrils, as well as decreased egg production. The chick we bought from her has been sneezing these past 3 weeks, but its been once a week, not daily or constantly. No one is showing any other symptoms other than what I have stated and everyone is healthy red in the face except the chick we bought from her. Could we possibly be infected?
