Santa singh planting the chicken

Santa Singh decided to start a chicken farm so he bought a hundred chickens to begin with.
A month later he returned to the dealer for another hundred chickens because all of the first lot had died.

A month later he was back at the same dealer for another hundred chickens because the second lot had also died and then Santa realised “I think I know where I’m going wrong,” said Santa, “I think I’m planting them too deep.”
