Hi Hillfooter - if you read my thread in the hen house section regarding Little Red you will see that he had similar symptoms, although his was also accompanied by very smelly liquid pooh. He ended up sleeping indoors being fed on chick crumbs, and having anti biotics, cod liver oil and vitamins. He is only young (22-24 weeks approx) not yet crowing and is going through the phase of growing his adult feathers. He originally looked like a beetle black but now has a lovely mass of red feathers around his neck and is getting more on his saddle area. Think I will have a problem every time he moults and at other times of stress, but he is so lovely natured he will just have to move indoors whenever it reoccurs.
