ZZ, Oh yea they love to run around. Are inside pens have a door which we open up and let them go out to exercise during daylight hours. Then we bring them in at night and they all head back to their own stall and we shut them in. Then in the morning when we feed we can get the little ones out first so they get their full amount without getting pounded by the bigger fawns. That works until they(The youngest ones) get to be about 3 weeks then we pop the doors off the inside stalls and let them all come and go back and forth until they are about 6 weeks old. Then we open up another pen(much larger) for them to live in. It's just that period when the bigger fawns are about 3 or 4 weeks old that they would try to jump out when they heard the little guys feeding. I don't imagine my plan would work if I was dealing with big numbers of fawns but for a dozen or so I do all right. Rick
