It all becomes clear

The guineas are building an army.Now the chicks are all transitioning from their brown juvenile feathers to the polka dot adult feathers (and looking quite scrappy while they're at it), and they are large.  And loud.  They move like a school of fish still and they're bold.  Bolder in numbers.They look like they're performing maneuvers half the time.  Flank the food dish!  Charge the walnut tree!  Establish defensive positions around Mom!  Recon missions around corner of greenhouse!  Circle back!I have to get rid of some, I mean, give some away, but I haven't got any bright ideas how to trap them.
