Delayed hatch

[havalinacat]

I have a brinsea mini eco and it seemsto keep right temp and humidity I cannot test at the moment as it is nit figital at all but I am following it's instructions but my hatch har been delayed by up to a week with first time only one hatching and in the second batch none and they were due 4 days ago, but all are still alive and moving when i candled them yesterday. What's going on? Is it the humidity that's wrong or the temperature that is too cold?

What temp was it at?

When you say you can't test it, does that mean you haven't checked that it is indeed at the correct temperature? You need to get a thermometer to check the temp, because a late hatch is usually the cause of the temperature being too low.

The temperature I know, I have a themometer in there and it's on quite exactly 99.5 however I need to turn eggs manually every day, then the temp goes down, but only for max 5 mins, then it's back. Its the humidity I haven't been able to measure, but the air sacs all look good size so I thought it seemed ok, but I understand that I need to test humidity, but can wrong humidity cause such a delay?

A late hatch is typically a temperature issue. Incorrect humidity can cause problems, but it won't cause the hatch to be late by a week.

Short instances of cooling (like when you lift the lid to turn the eggs) also wouldn't cause that much of a delay.

Are you using a trusted secondary thermometer to test the temperature?
