chicks can survive alot , and they are an animal, now dont get me wrong i love my birds and all , but you also have to remember they are not a live birth too, thunder can keep them from hatching along with other situations as well , so i dont actually think it is the hatchery fault , alot of time even if you hatch at home not all the chicks make it so die when pipping , zipping or even after hatched, then some still die off along the way of growing up ......... so it is all life , some die and some live , its not nessaceraly anyones fault , but under certain cercumstances it can be someones fault when the birds are not taken care of properly , but nature will always take its course and only the strong will survive .... sorry if i have offended anyone with this post
