Stuff coming out of hens mouth

[StickInsect123]

Hi everyone! My hen recently started laying and a few days ago I noticed some white, watery liquid came out of her mouth. I looked it up and I was pretty sure it was fine. Today I saw some brown liquid. Very watery. It has been rainy and it’s a bit muddy around the chicken coop run so could be because of ingesting mud? Other than that she seems fine, happy and she is eating and drinking and active. Is this normal?
Thanks in advance!

She's involuntarily regurgitating. Chickens occasionally will do this, and it's not of any concern. However, it could be a sign that a crop disorder is developing.
