My mom and I have many chickens and two of the hens have started acting broody. One is a serama and the other is a cute mutt. Anyway they take turns sitting on the eggs and pretend to be broody. We were wondering if it is normal for them to take turns sitting on eggs. Momma will sit on them for a bit, then dot will go in the barrel and sit on the eggs as soon as momma gets off of them....is it normal? Are they going broody? Are they just teasing us? Help!!
