כבשים קודמים לעזים – in every place, Scripture advanced lambs t goats, as it is written (Exodus 12:5): “[Your lamb shall be without blemish, a yearling male;] you may take it from the sheep or from the goats,” and similarly, (Numbers 15:11): “[Thus shall be done with each ox, with each ram,] and with any sheep or goat.” It is possible that the person who says, “This burnt-offering is upon me,” and he has and he has a male lamb or a goat, he should bring the lamb, specifically.

From here they derive that even a one-dayold ram is called איל... [You might ask:] Doesn’t Rashi comment on Bamidbar 15:11 that if it is under a year old it is called כבש, and only after 13 months it is called איל? [The answer is:] That is true only in regard to sacrifices. See Tosafos, Bava Kama 65b.
