This is an excerpt from a US Fish and Wildlife Service recovery plan for the great lakes piping plover.

It seems obvious from this that these eggs could be gathered up, hatched, fledged, and released back into the wild in areas that are open to ORVs and kite flyers. It is also obvious that it really is about keeping humans off the beach.

Captive rearing abandoned eggs.

From 1988-1992, in spite of the use of protective fencing, piping plovers continued to abandon nests and fecundity remained low. Beginning in 1992, the USFWS permitted Dr. Francie Cuthbert and her investigators to collect orphaned piping plover chicks and abandoned eggs and to raise them in captivity using previously developed techniques (Powell 1991). These efforts have shown that captive-rearing can successfully produce fledglings from eggs that would otherwise not hatch in the wild and that fledglings reared in captivity exhibit behavior similar to wild counterparts (Powell et al. 1997). In 1998, three of four birds reared in captivity and released in 1997 (total released 1992-1998 =18) were sighted at beaches in Michigan (Wemmer 2000). Two of the three appeared to have paired with wild mates and one of these pairs was observed copulating. While no nests of these pairs were found, observations suggest that at least one adult laid eggs that were destroyed before a nest was located (Stucker et al. 1998). In 1999, one of these captive-reared plovers was documented to reproduce successfully (Stucker and Cuthbert 1999). Similarly, breeding by six captive-reared individuals in the Great Plains was documented between 1997 – 2000 (C. Kruse, biologist, USACE, Yankton, South Dakota, and Robyn Niver, graduate student, University of Wisconsin-Madison, pers. comm.., 2000). Although only 25 of 360 captive-reared piping plovers in the Great Plains were sighted in the years following release, logistical difficulties in monitoring plovers over vast areas likely led to an underestimation of returns (C. Kruse, biologist, USACE, Yankton, South Dakota, pers. comm.., 1999).
