We just wanted to update all the poeple who took the time to provide us advice for our rooster.
After a few days we noticed that his skin was healing and he did not seem to be getting worse. He was missing all but a few tail feathers and one foot did not seem to work anymore and he just dragged it around the bath.
We did not give him anything other than food and water - we did not use asprin or other drugs for the fear of sending him into a fit by overdosing etc.
After a week of living separated from the girls, we let him go back out with them during the day. He really started looking up then. Our biggest concern was that they would peck at his sore feather roots...and we did see them do this a little. We kep him separated from them in a different pen for a few days still bring him in at night.
After a few days of getting used to being outside, we let him back with the girls. Since then he has been the king of the roost once more. He is growing feathers back on his tail. He still does not have use of his foot, although we notice him using it more...so maybe there is hope that might one day come good. He does spend time sitting down on the ground and in a box of hay...
We have noticed that he is 'throwing a leg over' the girls when he gets a chance (thats a cute euphemism for sex in our family...) but we have not noticed that the eggs have been fertile (that little blood spot). Maybe we are missing something here.....but just hearing him crow and seeing him acting normal makes us feel so good that we did not put him down (as some vets suggested).
Now, as for the dog. We called the the local sheriff to ask what the law said we could do in this situation. We were toild that we could shoot ('to kill') any animal that came onto our land and threatened our livestock. Being animal lovers, we could not do that...and do not have a gun that would kill anything (the BB rifle would not put a hole in warm butter at 10 paces). So we took another approach. Firstly we contacted the owner and let her know what the issue was. She was very upset and has kept her dog under greater control. Secondly we raided the wire of our pen by a few feet, so that if the dog (or other animal) comes they have to jump way highter to get in. (Our chickens are locked inside the chicken house at night...so its just during the day).
So thats the end of our story........
Thanks again to all.
