I have been watching my Genny pretty closely for a little over a week because she looked like she was starting to show signs of gape worm - nothing more really than she was just holding her mouth open a lot. Anyway, she has been very stubborn about not letting me see in her mouth, and i couldn't figure out how to force it... Anyway, the other girls started panting more this past week - 'cause this is Texas, and it is HOT outside. And i noticed that the other girls display their tongues, and their "chin" areas show some movement when they're panting. And then i caught a couple of glimpses, and just now i got a really good look inside of Gen's mouth, and there is no tongue in there! It's just a cavity. And her throat area is bigger than the other girls. Have you ever heard of this? Do i need to do anything? She seems fine, except that she holds her mouth open more than the others. She eats and drinks and poops. What do you think? All 3 of my chickens are 14 week old buff orpingtons.
