I have never had a doe discriminate between bucks- until this year! Ive had two or three does now that were not at all interested in certain bucks One doe I couldnt even hold to stand for the buck I had planned on breeding her too, but I picked a different buck and put him in the pen with her and she let him breed her multiple times. Today I took one of our junior bucks into the doe pen to see if any of my does I already bred were coming back into heat- and this doe was all over him wagging her tail, it took everything i had to drag him out of there without her in tow, she loved him. So I said well I may as well breed you- I went and got the buck I WANTED to breed her too, and she wanted no part of him. I was able to hold her- and he succesfully bred her, but what the heck?
