Right now I have a seed and crushed scratch mixture in a maxwell house coffee container with a handle. I noticed that when I shake it, they hear it and it gets their attention, but I think I'd get further with a metal container of some kind. I'm having a hard time finding a metal one that's not too big, not too small, plus has a handle. I noticed that when when I tap the galvanized hanging feeder, it is more effective at getting their attention, but I'm looking for something portable. What do you use to call your chicks? "Here chick chick chick" while shaking the can is not eliciting the response I'd hoped either. Maybe I should work on my pitch? Maybe I just need more time to train them? Does this go in the "managing your flock" section? not sure.
