I am building a first aid kit and I have looked everywhere on what kind and brand of clippers to get to have on hand for damaged beaks and nails. Every where says get dog clippers. What size? What brand is recommended? I don't want them to be dull. Also a sharp pair of scissors for cutting wattles and combs. I had to dub a chicken from an injury and I am not sure what brand of scissors to buy and type. Thanks for any information!
