Ok it's my first year breeding and a few of my girls are getting huge and went few ovulation a month back so i have a few questions.

Firstly how long after ovulation do bp's normally lay?
Secondly when you introduce the eggs into the media inside the egg box is it not initially to cold for the eggs? Do i need to warm up media before adding the eggs to it?

Thanks in advance and sorry about the generic "newbie question"
