Poultry

[Amir Sohel]

Low humidity in an incubator causes excessive moisture evaporation from eggs, resulting in large air cells, dehydrated embryos, and “shrink-wrapped” chicks that are stuck to dry, tough membranes

[Md.Rejuan Hossain]

If humidity is too low in an incubator, developing embryos lose too much moisture, causing the air cell to become too large, the internal membrane to dry and harden (shrink-wrap), making it difficult or impossible for the chick to break through and hatch, often leading to it dying in the shell. This results in a poor hatch rate, smaller, weaker chicks that can’t fully develop or hatch, or death before or during pipping.
