Dear chicken wizards, What is the weight range for hatching eggs? I have pullets/young hens that I hatched out last spring and would like to hatch some of the eggs, btw they are standard BBS orpingtons. The eggs are not the tiny pullet eggs they started out laying, nor are they the super extra jumbo monsters my 2 yrs old buff is laying. Usually around 60 gm. This is my first year hatching my own eggs so I haven't a clue. I just know you don't want them too small or large.
