For the past couple of days I've been seeing this strange, runny dropping in the coop. I tried looking in these forums but without pictures I have no idea if the issue they have is like mine. I've narrowed it down to either the rooster or a specific hen, but since it's been so cold I can't exactly sit in the coop until this mysterious poop's owner shows themselves. We have seven hens, with two separated due to pecking order issues so we know it's definitely not them, and a rooster. This is what the poop looks like: It's bright yellow-green, has the look of very fine grits, and as you can see it's liquidy however I haven't noticed any unique smell coming from it. Then again I haven't exactly stuck my nose right up to it either. I don't see any obvious parasites or blood, and the chalky white bit was hard to spot but it was there. Nobody appears to be lethargic or showing definite signs of disease yet so they haven't been dosed with anything. Could someone help me diagnose this before a serious issue pops up?
