I know you're going for the joke, but it's way to close to why a lot of these people want to outlaw reproductive healthcare.
In reality, humans have more children in bad circumstances, and less when we're educated, have life options, don't need children to work as labor for the family, don't need them to provide for us when we get old, and have confidence that they'll survive.
In bad times we have a lot of children for better odds and more hands to do work, and in good times we have fewer to concentrate our resources on.
It's why they want to ban reproductive healthcare and tank the economy: in 20 years there'll be a wave of economic demand and labor supply. That the individual will be broke, have no future, and no education is irrelevant.
It being the same species as me. There's no objective reason I'm "better" than a chicken since value is a subjective measure.
Since it's subjective though, it's not unreasonable to say that as humans, we value humans more than chickens.
We'll never escape the subjective nature of value judgements, but as long as we're honest about their subjectivity we can work with it.
A moral system that requires me to pretend that when you, my child, and a chicken are trapped in a burning building that I'll be unconcerned about who gets rescued first is a non-starter. Likewise, when it's me, your child, and a chicken it's a non-starter to assume you'll have the same priorities as me.
