I noticed a few days ago the Mille Fleur Cochin bantam trio were shaking their heads quite a bit. I assumed it was because they were in the rain for awhile and maybe had rain in their ears. Their ears had a yellowish crust around them... Tonight I pulled my cockerel out to check on his runny nose (he shielded the girls from the rain and got drenched. He ended up with a runny nose and was shivering). I noticed he had a powdery residue on his comb. Niiiiice. I head to town to pick up some Vaseline and Sevin. I already had Poultry Dust. I don't know what kind of mites they have, but I olive oiled their ears, Vaselined their combs and faces, dusted them with Sevin and dusted their bedding with Poultry Dust. Now... It is mites, right? Should I redust in a few days? Or will the dust in the bedding be good enough? They are separate from the other 72 chickens and they aren't showing symptoms, but should I take precautions anyways? What I don't get is this... The trio was out in the dog kennel and were shaking their heads right after coming in out of the rain from there. The big girls are now allowed to forage in the kennel. Again, they have no symptoms of ear mites. Do ear mites cause a yellow crust around the ear? I also never got answers on Milton's runny nose. He had clear discharge that is now gone. All three are eating well, drinking well, have normal, solid poop, no chest noise when breathing, no eye discharge, ect. BUT... They are gaping their mouths more now and if I have to make Milton run around the coop as he's trying to stay away from me, he gets labored breathing quickly and then gets a bit of a rasp in his breathing. Should I be worried about something more serious? The girls only have head shaking and mouth gaping, to clarify. Milton had the runny rose for about a day and a half, quickly developing labored breathing with a mild rasp if made to move around a lot, head shaking and mild mouth gaping. All of this started after being in the rain last week during the Katia/Lee rainstorms PA got that caused all the flooding (Tuesday night into Wednesday). Thanks in advance!
