I have three does in with my buck. He is over a year old and has been running with them for 6 mos. He is aggressive and stays after them. I saw him breed a doe 5 months ago and my daughter did ultrasound. Says none are pregnant. He seems fine as far as a buck goes. Oh and I have not seem them come in heat except one doe that just had babies 3 mos ago came in and he bred her but that would only have been 2 weeks ago so to early to tell if she is prego. What's wrong ya think?
