LOL Current pictures are always best.
If she continues to "gape" or stretch her neck, you need to be investigating. Check her crop for several mornings in a row to make sure it's empty. Watch to see that she is eating/drinking well and has a source of grit.
If the stretching of the neck...
She's just a baby:)
I would re-check the crop first thing in the morning before she has had anything to eat/drink.
Stretching the neck can be adjusting the crop. Make sure the chicks have access to grit, them helps them process food and whatever else they eat;)
Hi @Crazytexanchickenlady :frow Welcome To BYC
If you have photos of your chicken or a video of her actions, that would be good:)
(for video, upload to youtube, then provide us a link)
How old is she?
What type of food/treats do you feed?
Do your chickens have access to a source of grit...
