Yesterday, I noticed my hen wasn't acting like her self. She seemed a bit down. This morning I found her just standing in the coop, tilted back like she was going to do a poo, but nothing came out. She isn't moving around and just sits there with her eyes closed. She looks like she's in pain but I don't know what to do. I offered her some of her favourite food ( whole wheat) and she only ate a little bit. I separated her from the others just in case it's a disease. She has been pooing out this white stuff. Does anyone know what it is?
I found this under their roost.
A couple weeks ago I added pine shavings in their coop for the first time. I saw they were eating it. A day or too after they stopped. Could this be the problem?
