I got the first egg from one of "the babies"! Saturday, I found the smaller, darker egg in the nesting box, and Sunday I found two incomplete eggs (just the insides, no shell - very weird, but common for the first eggs) in the boxes.  My babies are all grown up!  They are right around 24 weeks old, so I was expecting to start getting eggs soon.   The newest addition to my flock are Summer Welborns, and they usually start laying when they are around 6 months old.
