We don't give chooks enough credit for intelligence.
Our neighbour had a Chinese silky rooster who was really tame and would let you pat him. She also had a huge bitch of a female rabbit who had an aggressive temperament and often growled and charged at the chickens.
She made the mistake of attempting to put the frighteners on PooLing and he cooly turned his head and gave this giant rabbit one peck one the head as an act of castigating her and the rabbit left him alone after that.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
