Q. Since Rav Miller paskened (ruled) that you can do shiluach haken on a nest with geese eggs, can various people do it, each taking just one egg? When they return them as you wrote, can someone else also repeat and then put it back?
A. Shulchan Aruch (Y.D. 292: 1) rules that one complies with the mitzva of shiluach haken by just taking one single egg. Sefer Shaleach Tesahlach (p. 15) quotes Horav Chaim Kanievsky Shlit'a and other Gedolim, that indeed a number of people can comply with the mitzva, each taking just one single egg.
One complies with the mitzva when sending away the mother-bird, and taking and lifting the egg with a proper kinyan. (An acquisitive act, such as lifting it over three tefachim - about 30cm. or 12 in.). If one then proceeds to place the egg back into the nest and is mafkir (removes his ownership) from it, if the mother-bird returns and sits on the egg, Horav Shlomo Mille'r Shlit'a opinion is that, a second person could also now comply with the mitzva.
