I have a 5 month old pullet whose head is very swollen and puffy including ears and wattles. I don't think the swelling extends down the neck. I cannot find any injuries or parasites. She does have a tiny bit of clear discharge out of one nostril and there is a tiny bloody spot up in that nostril. The other side is normal. Her eyes seem fine, no discharge there. She does not appear to be in pain and is eating normally… Any ideas?
