The Society was founded as the Stamford & District Co-Operative Egg & Poultry Society Limited and was first registered on 23 August 1916.

The object of the Society was "to carry on the businesses of wholesale and retail dealers in agricultural requirements, dairy, farm and garden produce, eggs and poultry, and in any other classes of goods the Committee may direct..."

In its early years the Society had its offices at 51 High Street, later occupied by Thomas Lyall auctioneers.

This shop was demolished at the same time as other properties on the street in 1966 although it had been an important medieval house.

The whole range of buildings was replaced with a modernist building, which many consider quite out of character but a floral design mural was rescued and placed in the museum. Tesco now occupy the east site of the building which stretched as far west as the old NatWest Bank.

In the 1930s the Stamford Egg Society relocated to Radcliffe Road and then in 1955 to Halliday's Yard, at the junction of Radcliffe Road and North Street where the eggs were tested, graded and packed.

In the 1953 egg marketing cooperatives handled 40% of the eggs produced in the country and the Stamford society was the fourth largest with over 2,100 members.

The Society remained at this address until it was wound-up in 1974, its assets being sold to Messrs T Faulkner & Sons of Stewkley,
