I recently (about a month ago) acquired a 5-6 month old BA rooster; up until about a week ago he seemed just fine, however he is now sneezing fairly often during the day, he also shakes his head sometimes and has a slight clear nasal discharge. It only seems to be happening during the day as I have spent some time out by the coop listening after he is on the roost and I don't hear him do it. I have 13 pullets who are just fine and acting normal, he also acts normal. Still eats, drinks and mates with the ladies and acts like there is nothing wrong. I'm not sure what's going on or what I should do, treat for something or wait it out and see what happens ? I did notice not long ago that there was an ammonia smell coming from the coop... I use deep litter method but it has been so damp here lately that it has been causing some dampness in the coop. I have since turned the shavings and added new so there is hardly any odour at all... Could the ammonia be contributing to this ? And if so, why are none of the girls showing any of the same signs ? Any help/input/info will be appreciated.
