Hi, I have searched and searched and cant find anything similar. We have a bantam with a swollen head. First noticed a few weeks ago and seperated from the rest of the flock. This week I have tried tylan orally and pretty much made no difference. No sneezing, no watery eyes, lays and eats normally but her head is about twice the size. Today noticed blood from what appears to be damage from rooster or other hen. Any tips please?
