A chicken farm that could house 330,000 birds could be licensed next week.
Six large sheds could be built by Northrope Farm near Donington, which is looking to diversify its business beyond crops.
The sheds would each house 55,000 day-old chick birds until they are ready to feed.
The site off the A52 Fen Road would be upgraded to cope with traffic if plans are approved. It would be widened by 20 meters on either side of the entrance to allow the passage of heavy goods vehicles.
Simon Walsh, who represents Donington on South Holland District Council, said: “While investment in local businesses and jobs must be encouraged, we must be mindful of animal welfare and noise/air pollution. /environmental.
“If planning is agreed, it must be with conditions centered on animal welfare, regular inspections and the power to act in the event of default at any time.”
He said residents need assurances that there will be “little impact on the environment and any smell or noise that will affect the local quality of life”.
Jane King, who represents the village on district and county councils – and sits on the parish council – said: “I understand the need for farmers to diversify now, but I have concerns about the welfare of so many birds, and I would like assurances that this will be carefully monitored and that action will be taken immediately if there is a problem.
“There are concerns about the smell of these sheds, as well as the extra traffic coming onto the main road.”
Eleven objections had also been received from members of the public, raising potential issues such as odours, traffic problems on the A52 and flies.
A comment stated that an outdoor chicken farm would be more humane and preferable.
Donington Parish Council has also raised animal welfare concerns, saying it doubts the council is monitoring and enforcing the rules.
Despite this, officers from the South Holland District Council say they see no valid reason to deny permission.
Previous farm house building applications have been removed from the application, but may be submitted separately in the future.
The plans will be presented to the planning committee of council on Wednesday, September 7 for a final decision.
