That's what I love about this website. My lovely rooster was doing the same thing, so I popped in here to see if I could find out why. Thanks for providing the video. I feel much better - although ours have tons of grit available - maybe just a piece of stuck lettuce.
Is something wrong with my chicken? Weird mouth thing - VIDEO included - Page 2
The rest of the flock is fine and this morning I discovered one of the year old hens acting like she wanted to crow. I watched her for a bit longer and though perhaps that was not the case. Yesterday she was eating and drinking just fine; her comb and wattle are a healthy color and other than molting, she is in good condition.
I have had others tell me that when a young rooster is trying to crow it sounds like someone gasping for breath. Yes, I looked down her throat and see no worms... Any ideas? I live in a very rural area; the local vet does not treat chickens.
