Second Reading 14 If the offerer cannot afford to sacrifice an animal from the herd or flock, he may sacrifice a fowl. If the offerer’s sacrifice to God is an ascent-offering from fowl, he must bring one of the mature turtledoves or one of the young pigeons, of either gender. The fowl does not have to be unblemished, but it may not be missing a limb. The offerer does not lean on ascent-offerings of fowl, as he must for those of cattle, sheep, or goats.
Turtledoves become suitable as sacrifices only once they reach the age at which their feathers have finished turning yellow. Pigeons are suitable as sacrifices from the age at which plucking a feather causes them to bleed until the age at which their feathers begin to turn yellow. Thus, both turtledoves and pigeons are unsuitable as sacrifices during the beginning stage of their feathers’ color-change.
