Hi there, welcome to BYC!
The hardest part about breeding with a purpose is HAVING to make decisions that are for the good of the whole flock... which will sometimes include culling newly hatched chicks.
50% of everything that hatches will be male as well. So start preparing yourself mentally. You know what you will HAVE to do, so work your way up to it. My teenage daughter was a highly sensitive person and I thought we might be vegetarian before all was said and done. My husband does not participate in culling at all. Alas, we still enjoy eating meat but are more aware of where our food comes from and thankful for the circle of life understanding (and acceptance) that came with it making us more conscientious consumers.
Our first culling was awful with plenty of mistakes.

But with practice... it is a SKILL I value greatly... now if one of the birds I hang out with daily faces an issue... I have the confidence to help them out, knowing I'm not causing anymore trauma, drama, or pain.
That being said... poultry is NO easy way to make extra money in my experience and you'd be lucky to cover your cost. ANY farming is a labor of love.
You might be able to find a neighbor, friend, uncle or something that you can prearrange any need culling. I did have someone doing the processing for me and was worth every penny. But ultimately waiting on their schedule became VERY inconvenient. Dispatching and such is not desirable but it is needed. You learn to do it as any terrible job like cleaning the toilet or changing poopy diapers.
Watching something die slowly is never an appropriate option. But once you wrap your mind around things you start to see LIFE instead of death. Everything dies eventually. But for example now instead of seeing a dead animal on the side of the road... what I see is carrion. Something dies so others can live.
Learn about humane euthanasia. And decide the difference between culling and killing. Culling is with purpose. Killing is senseless.
Hope this helps a little. It's good to have goals and that you are working on growing yourself! Hang in there and good luck, you got lots of support here to get through that first time and such!
