The Farm Unit has been garbage for years. I bet they are only successful on days when new birds arrive. After that, it's like watching the Goose Parade from roost to feed, by-passing most hunt-able spots. It all depends on the holding ponds. If they are full of water, the honky tonks will stay on the refuge after the morning flight from Cibola Lake. Those ponds were implemented to keep the geese on the refuge, the refuge manager at the time felt like they were his geese and wanted to make hunting very difficult....he succeeded.
Don't get me wrong, if you're at the right place at the right time, you can be done on a single flight of birds. But now a days, the right time is like a full star alignment...new birds, right place, right wind, no bozos next to you, good decoys, good calling,,,,yada yada yada...
Cibola actually has some CA areas to hunt, but yo need to know where you are. The Fed wardens are an extra cocky bunch...
If you want to shoot some honks there, I would look into the Cibola Sportsmans Club for a guided shoot to get a feel for it. Not sure is they still do guided hunts??
BTW, you're going to want some quality Full Body decoys or good floaters, I wouldn't waste the effort with shells or silos there...
Good luck!
