I know, it makes me ridiculously happy : )
Hatching in cartons for me is more of a space issue than anything else. Eggs take up less space 'upright' than they do laying on their side on the wire. This week I have two hatchers going. The big hatcher is almost full with cartons and a LG-full of eggs laying on their sides on the wire ( I put all my Rock and Am' eggs in the LG hatcher this week, so no panic of being able to tell *pure* chicks from *project* chicks ).
Third chick out is another Fm NN Green-Egger --- not smut black skin, but still Fm.
Day 21 doesn't begin until midnight tonight, so these first out are just eager : )
