This Research Topic on Avian Incubation Conditions is an inclusive treatise discussing the impact of several environmental factors during egg storage and in the incubators that may affect avian embryo and post-hatch development, physiology, metabolism, and growth. The objective of this project was to gather current relevant research on this topic, detect areas lacking knowledge or understanding, and propose methods of study to advance on embryology and avian incubation techniques. The impact of egg storage conditions, incubation temperature, hypoxia, moisture, and light, among other factors, were reviewed in this Research Topic. Embryo developmental and long-lasting effects of these factors were systematically revised. A total of 12 manuscripts were accepted for publication: 7 original research contributions; 3 reviews; one mini-review; and one paper related to methods. Three papers presented recent findings related to egg storage effects on egg quality and embryo development. Egg storage is a common and necessary practice in poultry production to synchronize hatch, meet and regulate hatchling demands, and coordinate activities in the hatchery. However, prolonged storage and conditions during this period may significantly impact embryo survival, development, hatchability, and even life post-hatch. Minimizing these harmful effects has been a frequent Research Topic in avian incubation. Pokhrel et al. elucidated the molecular and cellular mechanisms involved in the better recovery of embryos during storage when eggs were exposed to 12°C rather than higher temperatures (18°C). These temperature-dependentmechanisms are related to the embryo’s transition from blastulation to gastrulation. Studying the sequential effects of egg storage on egg quality and embryo development on the same eggs is challenging since most methods to evaluate egg quality are destructive. Adriaensen et al. used non-invasive tools such as computed tomography and magnetic resonance imaging in a study to evaluate the effects of egg storage duration on egg quality and embryo OPEN ACCESS
