I only had biddies at the time, but I just adopted some rescued hens. They have signs of rooster wear on them, but I've been having a really hard time looking at the eggs telling if theyre fertile, I can't find the bullseye anywhere. But I just adopted them a few days ago. I'm worming them right now anyways, and I've read not to hatch when worming because it can lead to deformaties. Once they're done worming, I'll probably set some eggs. They're really nervous and I don't want to stress them yet until they can calm down a bit.
