title: [The embryonic development of birds in weightlessness].
abstract: During the period from March 4 through 24, 1990 an egg-to-egg cycle of quail incubation on the orbital station Mir was completed. Out of 35 eggs, that developed in space, 8 normal hatchlings emerged, 6 of which were able to get out of the egg-shell without any help. Subsequent observations showed that the hatchlings could not get adapted to the weightless environment or know to remain fixed to the wired floor, due to which they were unable to peck.
