Silkie chicks hatched missing toes

[Shaftermoko]

Ive had 5 chick hatch over the past week the first is a normal happy black Silkie then I have 4 blues that 3 are missing one or two toes and one that has one foot that the toes are cripple on and walks on the side of the foot. What would cause this? Please any info would help!!

I have had this happen when there were fluctuations of temperature being too high during incubation.

:/Well that sucks that means the hens are keeping them to hot or something. Any suggestion??

Could be genetics, could be incubation temperatures being too low during the first few days (1st five I think I recall?) . Crippled foot could be hen or chick nutrition or mechanical or incubation problem.
