Good to see another Pennsylvanian antkeeper on the thread! Welcome to Formiculture! As of development, yes, that is very fast. Although I have kept Formica pallidefulva in the past, and they also developed pretty fast. From what I've seen, the genus Formica in general tends to develop fast on heat. That might be the reason why they're developing fast.
Keeping:
1x - S. molesta (founding) 2x - C. pennsylvanicus (founding queen and colony)
4x - C. chromaiodes (colonies)
4x - T. immigrans (founding queens and colonies) ==> 3x queen [founding], 2x queen colony [colony], and two 1x queen [colony and founding]
1x - F. subsericea (founding)

no added heat but I do keep my room on the warm side 75-78 during the day, 70 at night they completely rejected any extra heat from a heat mat. The larger two queens have a couple cocoons each while the smallest has around the same amount of brood but she's slower just large larvae. Nice to hear similar speeds are also heard of within Formica I've kept some colony's before but right now its just the Formica that I have.
