The last tomatoes came in over the weekend, the vines are black from frost, and the hens are lined up at the garden gate like they know what is behind it. Tuesday is how-to day, and this one is about opening that gate.
Utah State Extension fenced chickens onto a fallow third of a vegetable garden. Insect sweeps inside the pens turned up 5 and 6 bugs against 30 and 26 in the open garden, bindw**d and prickly lettuce were well controlled, and soil potassium climbed. Mallow and thistle were only partly eaten, so the birds are a crew, not a miracle.
Oregon State found the same in an apple orchard. Codling moth and apple maggot larvae drop out of the fruit to pupate in the soil, right where a chicken scratches, and broilers ate almost 99 percent of the larvae offered. Hens took 90 percent in November and under 40 percent once winter set in. The window is now, while the birds are still busy.
1. Harvest everything you want first, then fence off anything still growing. Oregon State notes chickens eat young shoots and seeds too, so the kale and carrot beds stay closed. Utah State used portable electric netting and rotated the chicken section each year.
2. Give them weeks, not the season. Oregon State moved its pens every two or three days and found the w**d knockdown was short term and mostly grasses, with no difference a year later. Mulching after the birds left held the gains.
3. Mind the manure clock. Wisconsin Extension says the national organic rule is 120 days between raw manure and harvest for crops that touch the soil, 90 days for the rest, and its research found E. coli risk rose when fresh manure went on 90 to 110 days before harvest. Hens on the beds in late October are well clear of a May planting.
4. Clean out the coop into the same beds. Vermont Extension puts one chicken's litter at up to 130 pounds a year and says to work it in after harvest, never onto plants that are staying.
5. Or compost it for spring. Vermont's recipe is a 3 by 3 by 3 foot bin, turned every week or two, damp as a wrung-out sponge, for 120 days. Georgia Extension says a poultry litter pile should hit about 140°F within five days and hold there one to three weeks, which kills most pathogens.
Now the debate. Some keepers open the whole garden until spring. Others fence a section and move it. Our take: fence. Oregon State lost 37 percent of its free-ranging hens to hawks, foxes and raccoons by March, and Utah State lists predators as the first problem. A netted section by day and a locked coop at night gets you the bugs without the losses.
Which bed do your hens get first this fall, and what did they dig up in it last year?
