Want an easy method to raising mealworms for your birds and chickens? Here we have two similar methods. The first by Kathryn Kessler republish with consent from birdfeeding.org:
An additional commentary about mealworms, following the article in the most recent issue of The Bird's-Eye reView, came from Kathryn Kessler in Newton, Iowa.
"I have been feeding mealworms for two years now and find them incredibly easy to raise. I keep a supply going year 'round," she wrote.
"I have two plastic tubs (13 1/2 x 17x 6) with lids in which I use a mix of wheat bran and chicken feed (non-medicated) for the worm bedding.
I add sliced carrots, zucchini, celery or lettuce. "The worms cycle through to the bug form, which lays eggs in the bedding.
The eggs hatch into tiny worms that grow to adults and the life cycle then repeats itself. "In the spring and summer I sometimes feed as many as 100 worms a day when the birds are busy feeding their young.
I have had great success attracting several bird species to the mealworms. My favorites to watch are the catbirds that make trip after trip to the feeder, eat a few worms and then select two or three to take back to their nestlings.
My biggest frustration is with the robins, which are gluttons of the highest magnitude. I counted as one robin packed 25 worms in its bill before it flew away.
I have been feeding the worms from a shallow dish on the deck floor. But I am considering some kind of hanging feeder with an opening which would exclude some of the larger birds.
Mealworms have been a great addition to my birds' diets."

Now Let's get started growing our mealworms, Pour four to six inches of wheat bran into the container (add more later when you see that they need it), put the carrots/potatoes on top, dump all the mealworms on top, cover them with the grocery sack paper, and do nothing until the large mealworms turn into white, motionless grub that then turn into beetles.
Once you have several hundred beetles, start collecting/using the large ones that crawl between the folded paper by sliding them into a container.
Do this every other day whether you need them or not; they can be kept indefinitely in a ventilated container in the refrigerator.
Those being kept in the refrigerator should be taken out for two or three hours each week so that they can be fed wheat bran and watered with carrots.
Don't bother with the dead beetles; the baby worms will suck them dry, and their body parts will sift to the bottom of the container along with the feces dust and molting skins that the they produce from eating the wheat bran. Notes:
Stay up with removing most (not all) of them, or you will have a million mealworms on your hands in a very short time, and an odor will develop.
Each pair of beetles will produce several hundred babies. 60 beetles will produce several hundred babies for each of 30 days in a month, SO STAY UP WITH THEM.
During the summer, I just lay the lid over the top; during the winter, the handles of the Rubbermaid Jumbo Box have vent holes that provide all the ventilation they need.
Mealworms will multiply at temperatures rangingfrom 65 - 100 degrees F. The optimum seems to be about 80 degrees. I keep my house at about 74 degrees during the summer. I only keep them inside because it's more convenient.
All you have to do is be sure that they always have enough wheat bran and carrots.
