Our family just started our back yard flock a week ago. We have 6 girls and tonight I heard them squealing so I bolted out the door and saw a neighborhood cat who was so determined to have one that she gashed the tail feather area and its bleeding. I don't know what to do or watch for or how to prevent this. The girls are young - store clerk said about 5-6 weeks. They must have been too close to the chicken wire and the cat reached in and scratched her. Any help??
