Simplify - calving ease or not??

[thundercreekcc]

Hi everyone!
I’m looking to see if anyone out here has experience using Simplify on first calf heifers. Looking for your birthweights / calving ease of these calves! Thank you!

We've only had one out of a first calf heifer, came easy, unassisted, heifer calf, probably around 65lbs

We've had a few out of cows and they have been small as well, probably around 65 to 70 pounds
