ABC reports that construction is set to start soon on the nation's largest free range broiler hen plant at Blanchetown, about two hours from Adelaide.

The local Regional Development Australia chief executive, Brenton Lewis, said now other investors are interested in moving in too.

"The facts are that there's some identified investors, most of them from interstate, that are interested in chicken production in South Australia.

"And I think that's been made more possible because South Australia still has a requirement to produce more chicken meat from a processor viewpoint."

Mr Lewis said the land, in the District Council of Loxton Waikerie, and Mid-Murray Council, is ideal for these types of projects because it has access to three-phase power, water and good roads.

Another major attraction is that there's only one set of traffic lights between the sites being discussed and the processing plants in the north of Adelaide.

While the access to roads and power make the land attractive for investors, Mr Lewis said there are a few regulatory hurdles that make it difficult to establish poultry projects.

In addition to the usual planning and construction laws and bylaws, current legislation requires a 500-metre buffer between poultry sheds and houses.

"If you had a house on three out of four boundaries, it would then require that you move the poultry shed 500 metres in from there.

"So you can see you would then need a sizeable holding."

Mr Lewis said this makes selecting the right property essential for projects to move forward.

In addition, the ideal land is a mix of privately owned land and council land.
