It seems that around here, my predators are mostly airborn. I had a bald eagle attack my ducks this last weekend but luckily I didn't lose anyone. We have since covered the duck yard with bird netting for a visual barrier. The eagle has been back a couple of times but so far is too lazy to mess with the netting. I have two full grown embdens and I don't know if it will try for them or not. It isn't feasible to cover their yard as it hugs the corner of our house so I hope it will leave them alone.
