I have an americana 8 week or so old chicken, I use to have two, one flew the coop and my dog killed her, now the other one has been flying over my fence. I cant make a higher fence anytime soon so I wanted to know about clipping her feathers so I need help. Does this hurt the chicken? Are there any reasons why I shouldnt do it? How do I do it? Can I mess this up bad? Can I use just plain old sizzors? Will this work for sure? Please give me detailed instructions on this so I can give them to husband so he can get this done. Please note, we dont have any chicken experience at all. Thanks in advance!
