I've been keeping a starting colony of Formica fusca-group species for about 11 months now.

And their growth rate is nothing like expected - many people say it's a simple species that grows pretty fast, but even after a proper hibernation (3 months) the queen is not laying larger piles of eggs. There are just 10 workers and 10 pupae with a little pile of eggs.

It's not that the queen is not laying at all, but is the rate of development supposed to be like this at first?

I feed them sugar water and fresh worms or egg yolk every 3 days. They're still kept inside a test tube and the temperature is 24-27 C.

I don’t keep Fusca, but subsericea. I got them in April with 10 workers, (founded in summer of 2021) and they are coming up on 20. Maybe try switching foods? What do you currently use?

I feed them worms, chicken eggs, sugar water and sometimes pieces of apple or walnuts

Well, I looked it up and saw that many people have this kind of slow rate during first year, so they usually make a polygynous founding colony with several queens that don't kill each other somehow, and then introduce more and more dealate queens to the colony.

 

Here is a 9 queen colony of Fusca:

I'll try switching their diet a little

What about hydration? Do your formica have enough humidity? I have found this highly accelerates the growth of my F. Species

Go to the ant, you sluggard; consider its ways and be wise! It has no commander, no overseer or ruler, yet it stores its provisions in summer and gathers its food at harvest. -Proverbs 6: 6-8

Yes, they live in a test tube setup and there's highest humidity possible
