Brahma eggs slow development

[Ray987]

Hello, I started my 2nd hatch 6 says ago I have mostly light brahma eggs in there and few eggs from a hybrid unknown breed anyways I noticed that the brahma eggs are not developed as much compared to the other breed and compared to my first hatch (also unknown breed) my question is are brahma embryos slower to develop based on your experience?

I just hatched dark brahma and some blue columbian brahma. They where shipped eggs and where developing on time as normal. Also set silkie with them, they where shipped eggs as well and as per usual being that they are bantams some hatched a little early.

Notes: I'm running a 56ex incubator constantly and moving eggs to a NR360 for lockdown and hatch out. The 56ex is set for 93(99.3) degrees for this unit and humidity at 48%. The NR360 temperature set is 95(99.5) degrees and I'm keeping humidity between 65 and 70% for hatching.

Epp Edit: on temperature it's 99.3 and 99.5.
