emurim on the mizbeach. That is an impossible task for only 3 cohanim.

Maybe they held like Rabbi Natan (Pesachim 78b) - It was taught in a braita
Rabbi Natan said from where do we know that all of Israel can fulfil their
obligation from [only] one korban pesach,  The Torah states [Shemot
12:6]"all the congregation shall slaughter it [singular] bein ha'arbaim" -
does the all the congregation schect, is it not that there is only one
shochet? Rather it is to teach that all of Israel can fulfil their
obligation on [only] one pesach.
