This isn't a rant on the right or wrong of eating livestock.
Chicks hatch at a rate of nearly 60% cockerels and the rest pullets. When it's best to have 1 cockerel for every 10 hens. Something has to happen to the rest of the males.
Trade for what? Sell them? Unless they're a rare breed, they won't sell other than for under $5 in which case someone else will be eating your pets that you've spent a lot of money and love raising them in a nice environment.
I assume you're a vegetarian. I'm sorry if I offended you.
I hate culling day too. I dread it.
However, whenever I cull the extra roosters, all the mayhem calms down and there is once again peace in the flock. And they're great roasted with some sea salt, cracked pepper and rosemary.
