My Royal palm Turkey is sitting on a nest, I have her penned up and the tom is in there with her. She went broody with about 8 of her own eggs and I though 6 chickens eggs under her when she was sitting. Tonight I checked her pen and by the Gate there was a chick laying there dead and right next to it was a half broken shell with a chick still curled up inside the other half. There doesnt appear to be any sign of trauma. Any ideas? I do believe they are chicken chicks. She is nesting about 16 Ft From where I found these dead chicks near the exit to the pen.
