When utilizing an incubator for hatching eggs, one often encounters the dilemma of whether to remove eggshells after the hatchling emerges. Is it beneficial to leave them in place, or could this potentially compromise the health of the newly hatched chick? What implications might arise from the decision to discard the shells promptly? Do they serve any purpose in the environment of the incubator, perhaps offering some form of comfort or familiarity to the chicks as they acclimate to their new surroundings? Furthermore, how might the residual odor from the decaying shells affect the air quality within the incubator, and could this influence the wellbeing of other eggs still undergoing incubation? Moreover, is there a risk of bacterial contamination if the shells are not removed expediently? Should one consider the size of the incubator as a factor in this decision-making process? Ultimately, what are the best practices for managing eggshells in an incubator environment?
