Haven't found any spiders to give'em. But I've given several crickets to them. Taping the attack would probably be worth some money. They go nuts! Some even attack the bird running with the cricket so they can grab the meal.
Gave a beetle to them this morning too. same results.
Got 4 Butterfly nets at home for the Grasshopper season !
They are carnivores ! T-Rex kind when it comes to bugs !
Very cool to "train" them !
Had a BW hen that when she saw the nets out, she would talk to me (telling me to hurry ?)
Turn loose about 50+ of them in her pen, she would go round whacking (killing) them, then eat after ! Smart hen !
