What would you do? I have ten 14-week-old guineas that share a coop and run with a barred rock cockerel, 8 pullets, and two ducklings. They have all been in the coop together for about 9 weeks and have been in the run for about 4. Outside of the run, there are TONS ticks and other bugs (I got 52 ticks in an hour), PLUS a freshwater spring. But, the guineas just don't want to fly out of the run. The fence is only 4' tall. How can I get them to free range?
