Quote:Is a candler required equipment? I don't have one.
Plus our eggs are fairly thick shelled and brown- will one even work on those?
I agree with featherz here. If you just get a real high lumens LED flashlight (like over 100 lumens) it will work. The "mag-light" size works pretty good. It is not necessary to candle, but it does help to get the ones that are not going to hatch out before you go into lockdown. You definitely don't have to have an "actual" candler. I have a spotlight that I put the rubber bottom of a plumber's helper on to "focus" the light on the egg. That is my candler.
What featherz and dsqard said! I used dsqard's plumber's helper hint and I can see into most eggs enough to tell if something is going on. I'll go take a pic of my "candler". coz74 built a really nice box candler and posted a pic earlier in the thread....maybe he'll post it again if he has it handy.
