Consumers will be expected to pay more for chicken eggs after poultry farmers agreed to charge an extra 20 satang per egg, bringing the ex-farm price to 4 baht each effective from Friday.

A network of poultry farming cooperatives, which includes the cooperatives in Chachoengsao, Chon Buri, Chiang Mai, Lamphun and the Noi river basin in Ayutthaya, notified their members of the price increase, which equates to an extra six baht for a tray of 30 eggs.

Cooperative members will be notified if there is any further price change.

No reason was given for the price rise.
