We have red tails large enough here to carry off my mini Dachshunds so I know they could a duck or chicken I am glad to hear your lil weiner survived.We have hawks here in Tennessee that catch wild rabbits and will definitely go after chickens and ducks especially the smaller breeds! One got my miniature wiener dog one year! She survived but it was a difficult recovery for her! She couldn't move for several days...i had to spoon feed her and flip her every few hrs! Shes good as new now tho!
