: my year and halfold cow got into a pen with rodeo bulls. she is now bred. i need info on health. gestation, and births. please email me with info<p>How long was she in the pen? One hour or one day, etc.. Since you may not know which bull bred her it would be difficult to determine if they were easy calfers or not! If these are bulls that you wouldn't want a calf there might be a shot that could cause the cow to abort! On the other hand, she should be old enough to have the calf easily!<p>Good luck!
