A friend had a red tail hawk as a pet, got it when it was very young and when laws didn't protect them (long time ago)
It was fed stew meat or chicken parts...it never bothered the rabbits he had wondering around.
It was about 6 or 8 moths old when he decided it should be freed.
At first, the hawk had no interest in live food, even when starved for a few days...then the instinct kicked in!
Then it finally pounced on the white mouse!
After that, it even watched the rabbits with more interest!!!
The hawk was eventually released, it hung around until migration time, and came back every year for two or three years,...then it came back with a mate.
Around the fifth year it never came back...we hoped the 'old lady' decided they should nest somewhere else!
Long story short...yes, if gotten when young, (the proper permits are required), but after that first taste of blood as "Winged Defender"...I wouldn't bet on the chickens lasting very long!
