Has anyone heard of an allergy to chickens? My daughter has had a sinus problem for 8 weeks now, constant nose blowing, total nasal blockage, no air will go in. She's on an antibiotic which so far hasn't made a difference. The only thing different in our lives is the addition of 10 chickens. No problems when we took the chicks home at 2 days old. The sinus trouble began about 4 weeks later. We have no idea if the chickens are the culprit but today we told her she can no longer hangle them. She is sooo sad. They are her pets. She hugs them, cuddles them, etc. She has a broken heart until we can figure out what is causing her nose blockage and constant blowing. Anyone ever heard of this? We don't know if she is in fact allergic to chickens, and could it be that she wasn't until they grew feathers? Any info appreciated.
