For the last couple of days my 5 month old chicken hasn't left the coop more than a couple of times. She just sits on her roost all day. Large green, watery poop with whitish center, but she may have been eating the beets I put out for them all. She seems fine otherwise, curious and alert (she noticed my new glittery acrylics). She doesn't mind me touching her. Crop is normal. Seriously doubt she would have worms (has none of the symptoms associated with worms). What else could be up?
