Hi I'm new to posting on BYC and find all the current posts very helpful but I want to get a bit more specific to what is happening to my flock. I have 17 chickens, 1 of which is a rooster. All my chickens are different and lay all different colored eggs, I love them! 2 weeks ago I noticed my rooster got a bit "hoarse" when he would crow. Now he hardly crows at all. He sounds like he has a chest cold and sounds snotty (doesn't really look snotty though) He does try to crow in the morning. It's also almost like he coughs and it sounds snotty. 2 of my hens that are golden comets are in the same boat with rattled breathing. Yesterday when I picked up the golden comet it kind of smelled by it's face. They all look fine, eat and drink fine. They do everything they normally would just sounds like they have chest colds like bronchitis? I just wormed the whole flock with Safeguard on Tuesday 5/16/17 but don't see any improvement. I also noticed they were itchy and found mites/lice on them so I did a huge coop clean out and sprayed it all down and dusted with powder. I treated all my chickens with a poultry spray and even washed 3 of them and now they all look better mite/lice wise. What the heck is going on? I've never had this before and I've been a chicken owner for years now!! Please, any help would be greatly appreciated! I have 2 dogs (that are on flea/tick preventative and heartgard) but I don't want them to get any of this either!!
