8 1/2 month old NHR got into neighbors fenced in yard and was not really attacked or bit but the dog had her in his mouth. She was really freaked out of course. I checked her and found no signs of major injury, blood, just loss of feathers. Mostly tail area, the hollow shaft quill is still attached. We're newbies so not sure if we should just let nature take it's course, thinking they will grow back? Do the quills need to be removed? When we examined her she did not seem to be in any pain or distress and was eating normally afterwards. She was picking at the area a bit. There really is no pecking order in terms of chickens themselves but chickens chase cats and ducks chase chickens...so really cats at bottom of order Thanks in advance for your expert advice!! This is pix before incident. Will try to post post-incident tomorrow as this happened late in day.
