The primary concern when chicks are exposed to improper temperatures during hatching is increased mortality rates. Maintaining the correct temperature is crucial for the normal development of embryos. If the temperature is too low, it can slow down or halt the development of the embryos, leading to issues such as delayed hatching or even death before hatching occurs. Conversely, overly high temperatures can lead to overheating, which is similarly detrimental to the embryos.

While dehydration of chicks can occur if humidity levels are not managed properly during incubation, it does not directly result from temperature issues alone. Feather development is not a primary concern during the hatching process, as this stage focuses on the embryo's growth and viability. The growth of bacteria is more about hygiene and management practices rather than temperature specifics; improper heat may contribute to bacteria in the long run but is not the immediate concern during hatching.

Thus, the key aspect to consider is the direct link between improper temperatures and the increase in mortality rates among the chicks, highlighting the critical importance of maintaining optimal conditions for successful hatching.
