1. Hatchability of fertile eggs incubated with their small ends up (SEU) was 16 to 27% lower than for eggs set with their large ends up (LEU). In addition, the SEU position produced more non‐viable chicks. 2. There were no differences in post‐hat

The artificial incubation of eggs of domesticated species can now be carried out with a high degree of success. However, advances in understanding about the problems faced by the developing embryo during incubation are still being made; and some may
