I have a 1 y/o black sex link that, today, started opening her mouth wide as if something stuck in throat - in between, she eats, drinks, poops normal. Any suggestions?
integrated about 3 weeks ago, 2 black star sex links and 1 white plymouth rock hen (all 5 mo old) with my older 4 RI hens and 1 part orpington roo. Old flock not fond of new roosting buddies. Sudden onset swollen ear lobe of black star 4 days ago. 3 days ago got Duramycin-10 as suggested...
