Opposition is mounting to a proposed massive farm expansion which will house almost one million chickens.
Crown Chicken has applied to demolish existing sheds at Airfield Farm and Methwold Farm, at Feltwell.
It wants to replace them with 20 new poultry sheds to house up to 870,000 birds and four workers' houses.
But 59 people living around the site have objected to the planning application to West Norfolk council.
Grounds include the extra lorries which would be needed to serve the new units, along with fears over smell and pollution.
One opponent, Blanche Stoneman, said: "Industrial farming needs to be moved away from in favour of organic free range farming methods."

Crown says in a planning statement there is "high demand" for chicken and consumption is rising as the population increases.
It adds: "The proposed development will positively respond to this need and provides a modern poultry rearing facility which accords to high animal welfare standards, assisting the UK poultry industry in meeting the strong demand for British reared poultry products.
"The proposed four workers’ dwellings would enable adequate site management, 24 hours a day to support the health and wellbeing of the chickens.
"The proposal would be beneficial to the local rural economy and would sustain an already successful agricultural enterprise."
Crown, which employs 400 people, has also applied to build 14 new sheds to house 14,000 pigs at nearby Feltwell Farm.
King's Lynn-based land agents Brown & Co have also objected to both plans.
They say Crown Chicken does not own or have control over the access track to the proposed development sites.
"Access for the proposed developments cannot be delivered as there is no contractual agreement between the applicant and the third-party owner of the track and adjoining land," it adds.
A decision is expected later this year.
