Hello all. So I came home earlier to today and noticed that one of my hens is making a funny sound. She makes it repeatedly, almost as a cat would purr (it is not chicken purring to my knowledge, though I can't say I know for sure what that is lol) I just know I have never heard any of my 15-ish birds do this sound in the 2 plus years I have had chickens. She seems to be eating okay. She is blind in one eye and has always been more skittish of the flock when treats are dropped, so that is a hard thing to judge in general on her. Anyone have any thoughts? I am trying to figure out how to upload a video of it, so it can be heard. (Can anyone help with this, I have uploaded photos before, never a video though... but it seems to not be letting me do anything right now?) Thank you.
