Hello! I have some questions if anyone has any ideas that would be great! Last week I bought 10 new healthy laying hens and some chicks, I got them home and noticed some mites on the chicks so just to be sale I cleaned my coop and sprayed my hens and chicks with Poultry Protector! Mites went away and every thing had been fine I have continued to spray lightly around my coop with the spray once to twice daily to be safe. This morning I went to let my hens out for the first time and saw that 3-4 of them have a very swollen eye that's swollen shut and it's puffy around the area they area they have a little stuffy nose ans are kinda lathargect!! I'm very worried! My coop is very well ventilated and I haven't sprayed in face the other hens are perfectly fine and energetic? Was it the spray? Is it contagious to the other chickens? And can I get medicine for it? Is so what kind? Thanks so much if anyone has any thoughts I would greatly appreciate it!
