My chickens we attacked by a dog and two survived but they have a couple puncture wounds on their back. So far those are the extent of their injuries but the hen who had one puncture wound on her back has a limp and around the puncture its swollen. Is that normal? Will she be ok? Also the rooster has a couple puncture wounds on his back and he would get up very much. He hobbled a couple times to get food and water that weren't far away but fell. Is he just weak and frightened? Or is it something more serious? Thank you.
