A. I heard that Rav Miller discouraged people to do shiluach haken on geese since then they may be considered kosher birds and eaten, and there is no such tradition. Why did you write that shiluach haken does apply on them?
A. On question 2683 regarding if geese considered kosher birds for the mitzva of shiluach haken, even if there is no tradition to eat them, we wrote; “Hisorerus Teshuva (4: 155) maintains that a bird that has the simanei or signs of a kosher bird (See Shulchan Aruch Y.D. 82: 3), although if there is no established tradition to eat it, and we abstain from it (Rema ibid.), still one should perform the mitzva of shiluach haken as it is possibly kosher. (See similar opinion in Birkei Yosef (292: 10), Shach (ibid.14), Minchas Elozor (3: 43), and others).
Shalach Tishlach (p. 55) quotes that in such a case one should return the eggs or chicks after lifting them to the nest. Horav Shlomo Miller Shlit’a opinion is similar.”
Since Horav Shlomo Miller Shlit’a is out of town, I requested Horav Aharon Miller Shlit’a to ask his father if there has been a change in his position. He told that his father maintains that shiluach haken can be performed on Canadian geese as there is no brocho involved. but the eggs or birds should be returned.
