Heifer bred to early, still born bull calf.

This morning the young cow was turned in with the other heifers
after much mooing all night. She is doing fabulously and I am soooo
thankful. Thank you LORD.
The next several weeks I'll be setting up rotational paddocks on a
128 acre farm I am leasing. We plan to MIG (manage intensive grazing)
on the 100 acres of pasture. We will leave the bull with a group of
15 older cows but remove all the weined heifer calfs to my fields here.
I will need to stock these fields with more cattle from other folks. Charge
customer per poundage gained or just a straight fee. I am not sure which
way to go with that but seperating types of cattle will be a challange.
