Q. Is it proper to perform a Pidyon Peter Chamor ceremony (redemption of a firstborn donkey) in a shul.
A. Vayoshov Hayom (2: 15: p. 253) quotes that the Peas Hashulchan arranged a Pidyon peter chamor and they adorned the donkey with gold and pearls. Then. with a parade accompanied with trumpets and drums, the complete community took it to the Beis Haknessess, where the pidyon was performed. Similarly, Nohagu Ha'am (p. 175) mentions that in year 5736 a pidyon peter chamor was celebrated, at the Beth Hakenesset Chida in Bayit Vegan, Yerushalaim.
However, Yalkut Peter Chamor (p. 146) mentions that only some would do it in a shul.
Horav Shlomo Miller's opinion was that it depends one the minhagim and traditions of each place. Some may regard as improper to bring a donkey into a shul.
