Many reptiles in captivity undergo problems with egg laying.
Most of these problems are related to poor reptile husbandry.
A) Incorrect Temperatures.
If a reptile is not kept at it’s preferred optimal temperature zone (POTZ) it’s body doesn’t work efficiently.
It has difficulty performing normal functions i.e. digestion, parturition (laying eggs / giving birth), shedding, etc.
B) Incorrect Diet / Overfeeding.
Overweight reptiles also have many physical health problems e.g. fatty liver, dystocia and parturition problems.
Generally, improved husbandry & diet and medical management seem to resolve the majority of these cases. However sometimes surgical intervention is required.
