Yes, I just read about carrot with the pupae.aart,
"Another science experiment, Mom?" LOL. Sounds familiar.
Yes, you can cold store them in wheat bran and feed them every week. At 50-55 degrees they will develop, but very slowly. Keep a carrot in with them. They may eat a little.
Also, a good point I learned on this site is to put a piece of fresh carrot in with the pupa to keep them hydrated so they will develop properly.
By all means, get that 3-drawer unit out and rev up production! You can only feed mealworms to your chickens weekly if you keep several bins of different ages going. If you end up with more worms than you want you can always cut back. But unless you only have 2 or 3 chickens, I think the 5 drawers you have are gonna make some chickens very happy in a couple months.
Out of every tote you feed out, keep enough worms to pupate and start a new breeding bin. I ran out of worms once and I'm never gonna let that happen again!
I like the idea of growing 100 larvae into thousands and gaining some experience on a small scale to make large scale easier to manage.
I have 10 adults and 8 chicks....should be pared down to 10-12 layers and 1 roo by fall....don't plan on a large supplemental supply, just treats, but time will tell.
Was feeding some of the tiny larvae to the tiny chicks yesterday...once they figured it out they were pretty excited.
