Pesachim 76b-
The Chagiga is not brought on Shabbos since it has Tashlumin all 7 days. Why don't we say Chaviva Mitzva Bi'sha'ata just as we apply this concept to the burning of the fats [68b] which is done on Shabbos?
[Please don't suggest that the burning of the fats involves the primary and ideal mitzva during the daytime as opposed to the sacrifice of the Chagiga which can be just as ideally brought for the remainder of the week. This is certainly not the case. The conotation of the word 'Tashlumin' implies a bi'di'eved situation as in the context of prayer and fasts, etc.]
Thank you.
Sincerely,

You've raised an interesting question. However, the principle of "Chavivin Mitzvah b'Sha'atah" applies only when it is possible to derive from a verse that this Korban is Docheh Shabbos, but it is not clearly written in the verse that it can be Docheh Shabbos even when there is an option to bring it after Shabbos (such as the fats of the Korban Tamid that is brought on Shabbos, Milah on the eighth day which falls on Shabbos, and similar cases).
However, with regard to the Chagigah, the verse does not teach that it is Docheh Shabbos in the first place. To the contrary, it teaches specifically that it is not Docheh Shabbos (Pesachim 70b), as Tosfos points out (76b DH Ka Mashma Lan). That is, the reason it is not Docheh Shabbos has nothing to do with the fact that it can be brought tomorrow, because, as you say, that is no reason for it not to be Docheh Shabbos. For this reason, Tosfos (ibid.) erases from our Gemaras the words "since it has Tashlumin," for that has nothing to do with why it is not Docheh Shabbos. Even according to our Girsa'os, we must explain the Gemara as follows: Has the Chagigah had no Tashlumin, it would be identical to the normal Korban Tzibur which is Docheh Shabbos, and it would not be logical to learn from a verse that it is not Docheh Shabbos. We therefore would have used the verse (cited on 70b, that teaches it is not Docheh Shabbos) to teach something else instead. Now, however, that we see the Chagigah is somewhat different from the normal Korban Tzibur which is Docheh Shabbos, then we are justified in learning from a verse that it indeed is not Docheh Shabbos.
Once again, it is the verse, and not the logical argument, that teaches the Chagigah is not Docheh Shabbos.
Yasher Kochach!
