I raised BB whites one year. That year I lost a lot of chicks. Most of them I found in my water buckets and tubs outside (have ducks so need deep water). I thought they were accidently drowning after falling in and a new cat that had been visiting had gotten the others. I've lost a couple to drowning before but never at this scale. Then one day I witnessed the turkeys pecking one of my chicken hens so much her head was bleeding. I separated the turkeys. After that, no more drowned or dead chicks. That's when I realized the turkeys had been killing them and putting them in the water. If I ever do turkeys again, I'll keep them away from the chickens.
