The first hen to hatch out some eggs is this feral chicken. She has lots of maternal instinct and was the first to become broody. So I slipped 6 eggs under her and let her brood them. Of the 6, 3 hatched. Since I wasn't sure the eggs were fertile, I'm pleased with the 3 chicks I got. She's not the biological mom of these chicks, but she doesn't know that. She's taking wonderful care of them. As you can see, she's eyeing me up. I think if I stepped any closer to those chicks she would have attacked. She's a brave hen. It makes putting out food for the chicks a real challenge. But the chicks come running anytime they hear me calling "chick, chick, chick". That poor hen practically has a stroke when she sees them running towards me, she surely doesn't approve of such behavior.
I have two more hens sitting on eggs right now. One is a veteran at brooding and will hopefully end up with a dozen or more chicks. The other is a first timer so I only put 6 eggs under her. We shall see what happens in the next week.
