Need some advice please. Friday night I had a pack of dogs come on my property & attack my flock of free ranging chickens. Please note, when they are out, I am right there watching them, I just stepped inside to go to bathroom, in that couple of minutes, that's when dogs came. They killed 1 of my egg laying RIR's & a 4 mo. old Black Star (read tore them apart) & injured my 4 mo old Silver Laced Wyandotte. They tore a large bunch of feathers off her back & she has 2 gashes on her back, I'm assuming from dogs teeth. The problem is, she seems to be having with her right foot. She can move leg, but it seems to be gimpy, she doesn't have too much control of it. Could her leg be out of joint? She seems to be eating & drinking ok & pooping ok, it's just that foot she's having control issues with. Should I take her to vet to have checked out?
