Bought the 1 kg to see if my chickens like them, I've read some reviews on Amazon of different brands n some say their chicken don't touch the bulk bags... well my chickens loved these took right too them. I didn't have oyster shells but giving a handful of bugs a day they still had extra calcium deposits on shells n my gal that a new layer never laid a soft egg while eating these! Hoping to buy around the 4kg mark next time as that's a price I can afford n is a good amount of bugs (I pay $20 for 1.1lbs of bsfl locally for bugs that don't seem near has healthy or big or chubby)
I purchased these as a treat and great source of protein for my koi. Price is excellent compared to other retailers who specialize in fish food sales. Service from Chubby Mealworms Canada was, as I have come to expect and receive, wonderful. I highly recommend.
