Time to separate Haynes

This morning Donna saw that Haynes was getting interested in one of my cows.  He tried to mount her but fortunately she wasn't in standing heat - yet.  The first cow to have a calf this year had her calf a month ago - 30 days ago.  The cow Haynes was trying to mount was the third cow to have a calf this year - on March 14 - not even 30 days ago.   Normally cows don't come into heat until 45-50 days later.  But in 2020 I had a cow come into heat 34 days after having her calf.  Guess what, she then had her next calf early - January 30, 2021.  I don't want that to happen again.  So Donna and I herded Haynes into the south part of the corral to be by himself until June 1.
