No need now- every one is GONE!! Disappeared- not a trace. We found one and were able to revive it but every other chick is no where to be found????If you must collect them I'd try it at night and with a headlamp set for dim. That way you'd have both hands free, one to pick up chicks and one to hold your shield.
I have a fishing net screwed to a long stick for bigger chickens.
