I would honestly keep one and process the rest. I personally feel like too much time and money go into raising them just to give them away for free. And right now there’s not a market for roosters. There’s been such an influx of roosters this year.
The last one could be a girl. If you’re having that hard of a time getting chicks I would keep one rooster and hope that one is a girl and incubate some eggs next year. You’ll still end up with some roosters, but you’ll hopefully also have more girls.
I am so sorry but it looks like all are boys except maybe one.
The last one I don’t know. Could be a girl but I am not 100% sure
How old were they when you bought them?
