I have 4 guineas, I believe 3 are female and 1 male. I have noticed that the larger 3 guineas, 2 females and a male, rentlentlessly have been attacking our smallest guinea hen. We have tried separating the bullies from her but she keeps looking for the bullies and is anxious when the bullies are not around. She seems so anxious she ignores food we put out for her despite being prevented from eating with the bullies around. Does anyone have any solutions for me? We live in the city and cannot separate the guineas through large stretches of land.
