Ok, this is our third hatch. First hatch - nothing - long story revolving around oil on eggs. Second hatch - 9 out of 14 - we were pleased and the chicks are now around 4 months and we are looking forward to eggs! Third hatch - 39 eggs - due this wednesday - we are acting as surrogate parents for the lady we got our fertile eggs from since she has had a predator issue. New coop and now she's ready to restock her flock. Now for the question: I see egg cartons used in LOTS of your pictures. With the 14 we just put them on the grate thing. With 39 should I use the carton approach? Is it safer for the chicks that are still working on coming through? Or will the early birds still step on them? Any help would be so appreciated!
