הלכה על זבחים 231:17

From the laws of the commandment are the blemishes that disqualify a sacrifice that the Sages, may their memory be blessed, enumerated (Mishneh Torah, Laws of Things Forbidden on the Altar 1:2) that are seventy-three. Fifty of them are whether with a man or with a beast, and twenty-three are unique to beasts and are not fitting to be with a man. And likewise, there are blemishes that are unique to man that are not fitting to be with a beast and they are ninety, as we shall write in this Order (Sefer HaChinukh 275) concerning blemishes that disqualify a priest. And so [too,] that which they, may their memory be blessed, distinguished between a permanent blemish and a transient blemish; and that which they said (Zevachim 116a) that the blemishes do not disqualify a sacrifice of fowl, as it does not state about them, "an unblemished male." And about what are these words speaking? About small blemishes. But a fowl the wing of which has dried up, or its eye was blinded or its leg cut off is forbidden on top of the altar. And the rest of its details are elucidated in the eighth chapter of Menachot (see Mishneh Torah, Laws of Things Forbidden on the Altar 1).
