i have 5 turkeys 2 males 2 females and a young poult.the 2 toms hatched together and been with each other all ther lives {they are 18 months old} we added the 2 females in whith them about 2 months ago and it was fine then 1 of them started laying. but recently the 2 toms have started fighting and its getting serious they are slamming each other into ther fence of ther pen and letting the others escape.Ther is plenty of space for them to hide and escape each other in the pen so my Question is how do i stop them fighting?
