Do chickens yawn?

[eich831]

My chicks are about 6 weeks now and I've noticed that some seem to open their mouths as if they're yawning. No sound comes out when they do this. I'm pretty sure the one I saw tonight do this is not a rooster. Silly question, but just curious

thanks!

Yes, chickens yawn! They somehow manage to do it cutely too.

What looks like yawning is usually them adjusting their crop,
they often stretch the neck out a bit while moving their head/neck around when the beak is open.
