What else can I say, just when you think you know hens & their issues well, they do something unexpected & new! Got some new girls 14 days ago, they will be about 21 Weeks old now.they are currently still in isolation in a shed & runplenty large enough.this morning I let them out, they all hopped off the perch, toddled off to do what hens are supposed to do, and then I noticed a piece of what can only be described as intestine in the poop I scraped up!I looked at them all, no traces of trauma or blood on them that I can see.they all look & seem ok. Any ideas? Mysterious!
