You posted this "It is better to take the right horn of a ram, for it is bigger" here
However i could not find that in the prishah https://www.sefaria.org/Prisha%2C_Orach_Chaim.596.3.1?lang=he
can you please point me to the correct source
Thank you

The Perishah (and the Bach just before it) are in Orach Chayim, Siman 585, where the Beis Yosef is (just before the Bach), to which their comments pertain. Since this is "under" the Rema in Siman 596, I understand why you looked there.
To clarify matters, we will edit the outline to explicitly say
c:2:iii. Bach (585 DH...
c:2:iv. Perishah (585:5)...
