Thanks everybody for the comments (like I'm the one to get credit :-D)
She's been a good queen, just got them at the wrong time of the year (Jun 7th) due to weather. I have seen (or thought I did) eggs in cells(plastic foundation) that weren't drawn out but about half way. This is by far the frame with the best brood pattern. Others aren't as uniformed as this one. It seemed to be a race at one time between the queen and the workers as to who would get to an empty cell first.
