So, my parents decided to let the guineas loose today in hopes that they would free range and eat ticks. They did fine for most of the afternoon, but about an hour before sundown they found the chicken paddock and one of the cocks got in with the chickens and started harassing my hens again. We chased him out and tried chasing them back to the winter coop, but they weren't having it and ran up into the woods. The last place we saw them was up in the treeline. The chickens have been shut in for the night so the guineas won't be able to harass them and we left the garden and the winter coop open for them. Hopefully, they learn to fend for themselves in the woods and eat the ticks or find their way back to the winter coop.
