Another variation on this is in the works.  I am setting up an old 10 x 10 chain link dog kennel over area that is to be a garden next year.  It has a small stand of ragweed in it.  Generally, ragweed is not considered to be of much value.  I may have found a use for it as a location to more effectively concentrate the beetles in area easy for the chickens to pick through.  The chickens typically loaf much of the day when the beetles are flying, yet they have a hard time passing up a beetle that is very close by.  I am going to set up so the loafing area is essentially the same area the beetles concentrate in over in response to the lures.
Another observation of chicken ranging habits is getting more worthy of note.
