I am wondering how soon is a ram lamb fertile. I had a fourteen-month-old ewe lamb unexpectedly this morning. I sold my breeding ram back at Thanksgiving and the only possibility is that my ram lamb born the end of Feb. 2012 is the father. That seems hard to believe as the lamb born this morning was small but possibly viable if I had known and been there. I found the mother stretched out unable to get up yesterday afternoon. She seems to be one that occasionally picks a spot to lay down at and then gets just a slight bit off balance or whatever and then needs to get herself wiggled around to get up. The past couple of days have been hazy, hot and humid but they can get inside whenever they want. I am wondering if the stress had something to do with her lambing early. But I never thought my four-month-old ram lamb would have sired a lamb two to three month ago. That just seems hard to believe but it is the only possiblity.
