Don't shoot the calf!
There are plenty of people around (some less fortunate, but able) that will raise that sucker and give him a purposeful life. Being a pet, or simple raising it to butcher.
I'd GIVE IT TO SOMEONE who wants to do that before I shot it!!
Plenty of online communities around that u can put up an ad.
Heck there was one SOLD here awhile back faily local that someone gave 200 bucks for.
Give the cow another shot if you like. Or simply sell her....
Anyone remember the lil calf I had that lost use of his back legs. Well, he could walk around all day long but couldn't stand up after he laid down.
This was c-19 Era, when everyone was out of school etc.
I gave him to a family several miles away. They went out every morning and the several of them got him hoisted up so he could graze all day. They were his best friends!
Anyway. It was an awesome lil project for some folks that didn't have the means to purchase an animal. When he got too big for them to help him, they made hamburger. The kids tanned the hide.
They called me and thanked me for the calf. They thoroughly enjoyed the experience and bonding time with family.
