Sounds like yours have a lot of milk. I see a few like that - - biggest calves but may breed back late. Usually some continental in the mix. Seems like commercial cattlemen are leary about going more than 25% continential.

I probably have a bit better food than central minnesota too.. I find more than 25% british and I have pig-fat cows that don't make much for a calf.

This past spring breeding, we worked our heifers on 1/19 and started breeding them on 3/22
They averaged 780# (birth ranged 1/1 to 3/12), so a couple were 12 months old.
We bred all of them in a 6 day period. We used natural heats if they were due during the time frame, we used Lutalyse if their cycle timing was right, and we used CIDR for the rest. Out of 15 bred, we had to time breed two (1 settled on that breeding, 1 did not). We have 13 of the 15 due in a 6 day period. Extremely happy with the results. Did not start the cow herd until 14 days later because we were gone on vacation between heifer breeding and cow herd.
