A friend of mine bought a nanny the last week of July, and didn't think she had been bred. Later that week He saw her stand for a billy and breed. Counting the days would put her giving birth the latter part of Dec. Well, to his surprise, she gave birth to a healthy baby billy Sat. Nov. 26. That would mean she was about 1 month pregnant when she stood for the billy in July. Is there a false heat cycle that occurs? I thought if nannys were pregnant, they wouldn't cycle again? Why did she stand for the billy if she was already bred? We're confused, can anybody explain?
