1st Perek Summary: “Hakol Memirin”: Any adult can perform an “exchange.” However, just the owner, one individual, with an animal sacrifice (not birds or grains), even if it’s blemished, upon any other animal, male or female, of different valid species. “Exchange” doesn’t work with limbs or fetuses. An “exchange” cannot make another “exchange,” however; there is no limit to the quantity of “exchanges” that can be made to or from.
