I have about 10 Australorp chickens, and one of them went broody on a clutch of Khaki Campbell and Khaki/Cayuga eggs! She's been setting for about 2 weeks, and it will be interesting to see if she actually hatches them. I removed the chicken eggs, there was a couple under there, as I have no rooster. I have to cordon off the little area where she is so the rest of the flock can't get to the babies. Hopefully there will be babies. I wonder if she'll be surprised at their "ugly duckling" looks!
