I witness what I definately would call an ovulation from a pair of balls that have 7 documented copulations from Oct.-Jan. This occurred on 01/23, and she just finished her prelay shed today. My question is I thought they were suppossed to start the shed 20 days after the ovulation. She finished her's 16 days after ovulation.....has anyone had this happen to them? Do you think the pre-lay to oviposition time will be short as well?
