Me and your dad would get along good. Last year my later born/ fall calves brought roughly $100/ head more when I sold them in the spring than my big group of calves did the previous fall. Made me wish I had more.
I've learned there's nothing wrong with late calves cause it just gives you a different market to sell into. Any cow that doesn't calve by fall does get culled and my replacement heifers never come from the late calvers.
I've had late calvers catch back up to calving on time also. That kind of goes against her having poor fertility genetics because of 1 year she had poor fertility but then the next 2 or 3 years she has the best fertility in the herd and gets rebred roughly 30 days after calving.
Instead of figuring out how you're going to manage your so called cull cows that wouldn't net you much money if you sold them, figure out how you're going to manage the late calves to make you decent money. Whether you wean them at the same time as your bigger group and put them in a lot or you keep them on the cow to wean later.
