I have 2 pens, about.75 acres each. Back half of each pen is wooded and the front half is pasture. I have 14 grown deer along with 4 fawns. I bred with a yearling last year. Out of 3 does, one being the yearlings mom, he bred the 2 that arent related to him. One yearling doe that he bred had 2 buck fawns and a doe, the other one had 1 buck and 1 doe fawn
