Chickens and bees are part of urban gardening in neighborhoods, and some of those efforts are on display this spring.

David Cotton and Kelly Enzor's home, which is on the Grant Park 2013 Home and Garden Tour on May 11-12, was surrounded by just dirt for about 10 years, as their two dogs and two historic trees made it impossible to grow anything, said Enzor, a painter. After their pet boxer died six years ago, they turned their attention to the backyard. A shed and patio with a built-in grill, refrigerator, bar and fire pit were added first. About four years ago, the couple added a chicken coop to the space, which also has a vegetable garden.

“We originally were very concerned about starting to eat more organically and locally,” said Cotton, a vice president in a consulting company.

Their five hens typically lay a total of three to four eggs daily during the summer, enabling them to give away eggs to friends and family.

“We recognize that we can’t feed ourselves completely. If we can supplement some of what we have and if more people supplemented a little bit of what they eat, I think it would be a lighter footprint all around,” Cotton said.

Cotton built the chicken coop and the run, which stretches across the backyard. The chicken coop and vegetable plots, which grow greens such as kale, chard and lettuce and herbs, are both framed.

The couple use their compost as soil that tops the plant beds. In creating the yard, all the grass was removed and replaced with mulch and pine straw, lessening the demands for watering, and rain barrels collect water for the vegetable garden.

Beekeeping also is part of an effort to live in an eco-friendly way. Cameron and Joy Ayer will host a beekeeper talk and honey tasting at their Cherokee Place home at 1 p.m. on Saturday, May 11, and Sunday, May 12, as part of the Grant Park tour (grantpark.org/tour).

“I had two other neighbors on my block that owned honey bees, and we got a taste of that Grant Park gold and decided we would take it on ourselves,” said Joy Ayer.

According to Ayer, it’s been estimated up to one-third of our food can be attributed to pollination by bees. That’s why beekeeping “became imperative, not just a hobby,” she said.
