Abstract: There is provided apparatus for egg turning during incubation, comprising a plurality of egg trays, each having axially opposed pivots being aligned along a selected axis of rotation, support means for rotatively supporting said trays at said pivots, respectively, and oscillator means integral to said support means and said trays for continuously and smoothly oscillating said trays at a selected frequency through a selected angle about said axes of rotation, respectively. Preferably, said support means comprises a rack with a tray holding area for interchangeable trays in closely spaced, side-by-side relation and wherein said oscillator means is mounted closely alongside said tray holding area. Associated methods for egg turning are also provided, which are especially adapted for still-air incubation of a mix of egg species.
