Because they are so similar, and probably could be raised together, I would consider expanding your business into pigeons as well. You could make some good money for those women who need something to offer to the pastor as a sin offering and a burnt offering after their unclean time.
Leviticus 15: 28/29/30
28 But if she be cleansed of her issue, then she shall number to herself seven days, and after that she shall be clean.
29 And on the eighth day she shall take unto her two turtles, or two young pigeons, and bring them unto the priest, to the door of the tabernacle of the congregation.
30 And the priest shall offer the one for a sin offering, and the other for a burnt offering; and the priest shall make an atonement for her before the LORD for the issue of her uncleanness.
Probably easier than raising turtles, anyway!
I have no idea where you ladies come up with all of these animals every month.
