It was concluded that tilting and incubating eggs is not a viable alternative to conventional turning practices. Malposition II predominated in the tilted groups oriented 45 degrees or horizontally, whereas Malposition III predominated in the controls and in the tilted groups oriented vertically. Late incubation embryonic mortality was elevated in the tilted groups, and the frequency of malpositions increased. Depressions were cumulative and additive, with significant depression for all eggs tilted during the 1st wk of incubation, and diminished effects in the 2nd and 3rd wk. Tilting instead of turning depressed hatchability regardless of orientation. Comparisons were made in terms of the hatchability of fertile eggs, hatchability of transferred eggs, embryonic mortality, and malpositions. Eggs were oriented either vertically (large end up), at a 45-degree angle, or horizontally. At hourly intervals, eggs were tilted 45 degrees in opposite directions for consecutive intervals and returned to their original orientation. Six experiments were conducted to examine the feasibility of “tilting” instead of turning chicken eggs during incubation to provide a near-constant airflow pattern.
