Mushy chicks are the ones that hatch with larger than normal abdomens (visually).Too high humidity during incubation causes the chick to not be able to absorb the yolk as it would if the humidity was lower. This is why some peeps weigh the eggs during incubation to see if the water loss is normal or abnormal, it's another way of determining whether the humidity is right or not (weight loss). When they hatch they appear to be 'pot bellied".Thanks for the novel. I try to sink it all in. What is mushy chick syndrome?
I know at one point during the hatch the humidity was really high because over 50 of them hatched right at the same time causing a big spike. But I’m unsure how long it was like that.
They feel 'mushy', their abdomen will feel 'mushy' when handling them, thus the name.
The spike at hatch time isn't going to cause a problem ( while their actively hatching). The problem occurs prior to hatching during the incubation period, depending on the species of bird being incubated, that could be 14 days, 18 days, 21 days, 28 days, etc. The last 3 or 4 days that the humidity is increased, does not affect the embryos, unless the humidity is at saturation point...when you see water droplets forming on the viewing windows, it's too high.
