Three weeks ago when I went to henhouse I found my rooster , he's one year old, laying on his side unable to stand. Removed him to separate pen. For 8 days he could not stand at all, but continued to eat and drink. After the eighth day he started trying to stand but one foot is partially twisted. He now is up and running around just fine but foot is still twisted. Two questions: any idea what could have caused this? Do you think it would be alright to return him to the flock.....he sure misses his girls.
