Freeze the worms in tie wrap bags perhaps ... So that when it slows down in deepest winter you can feed the chucks on newly thawed ones .
You ought to also be able to dehydrate them and vac pack worth while amounts .
That could be an interesting exercise in making a simple 50 watt light bulb dehydrator and some form of cage to hold the worms in till they get dried & died out .
I did a bit of research on freezing them on the reptile forums - apparently the freezing process breaks down the fat after a few days. there was a comment that they wouldnt feed the mealworms to their reptiles after they had been frozen for more than a few days.
I also read that keeping them cool slows down the development of the mealworms - that would explain why they all seem to have matured at about the same time.
But chickens ain't reptiles & dont need the worms as a protein - just a treat.
Did find out why they mealworms were not being used quickly enough - I think my OH was giving the chickens too small amounts - they must have been getting about one each
