i put two chicks that was givin to me bc they couldnt keep them but they were the same ags within a couple of days but one iis much smaller than the rest and when i introduced them it was in neutral territory and were fine all day but when i went out to check on then that night she was bloody and curled up lifeless in the corner so i took her and put her up alone so she could heal. does anyone know with this continue to happen or what can i do to try to stop it?
