I remember now, mine weren't interested in any treat for a couple of months and they hated me. I remember feeling quite upset.That's what I was worried about MJ. I'm a briber with POLs. They simply can't resist a tasty mealworm. Chicks probably can't either but whether they should have them or not...
They were entirely uninterested in mealy worms. But the ones I had were dried.
So I got a small pot of live ones and offered them all wriggling on my hand. They became my instant BFFs!
