Is this chicken sick

[Oliver Hens]

Here is a short video of Flappy a 24 week old Easter Egger taken with a night vision chicken camera. She is roosting in the dark outside. I am in Florida and the temperature is in the 70's. She seems to hold her beak open a lot more than any of our other chickens. She is laying eggs pretty regularly. I haven't isolated any poop to check for abnormalities yet. During the day she is active but I seem to notice she hold her beak open more than everybody else. Please take a look at her and see if you think she might have a problem. Any advice would be appreciated. I am a chicken noob.

I'd love to know an official answer for this too. Every once in awhile one of ours will do this too but it never lasts more than a day or two. Mine seem to do it if they swallow something wrong!
