Welcome to BYC. It sounds like your survival rate has gone way up, so congratulations on the predator proofing. I hope your flock remains healthy and happy. Enjoy the website, and feel free to comment or ask questions in the forums whenever the spirit moves you.
Wow, very sad loss. Glad you have found a way to keep predators down. I've caught a few cats..don't worry so much about them getting my chickens..but they potty in my garden and have killed off some nice flowers/vegetables. Anyway, WELCOME TO BYC!!
