I too lost a pullet to a "crow" this weekend. My only true Ameracauna that we had named Mama, is now named Papa. Also, my RIR rooster has been doing this weird side step dance at me the past 2 mornings when I let them out. I can't tell if he's threatening me or trying to mate with me? He does the dance to the hens too. He's starting to scare me a little. Might be time to say Adios!!
