So my black hen (i think shes a bantam) kept sitting on her eggs for a month, but they wouldn't hatch....so we got 4 eggs from a family friend and 2 of them hatched out rhode island reds. The mother has been taking care of them for about 2 months, but now shes doesn't hang out with them and when she sees them she yells and pecks them and even Kicks them!!! Also, she doesnt sleep with them anymore. Can anyone tell me why she's acting this way? Please and thank you.
