GW It's been about 2 years. I have been very impressed With gsf, they really are very interesting critters
I would use them for bait, but pond still in planning phase
I plan to use them to supplement the chicken feed in The spring. I have seen some "automatic" chicken feeders With a gsf colony in a 5 gallon bucket over the chickens. When Mature they climb out and the chx get a snack
