More than 259,000 eggs were stolen from an egg farm in Turner.
The eggs were scheduled for shipment to Asia when they disappeared.
They were stolen from the Quality Egg Farm of New England, and were taken in two separate incidents.
Police say the second theft occurred while the first one was being investigated.
The missing eggs are worth about $25,000.
Police throughout New England are on the lookout for an unmarked truck hauling eggs without the proper paperwork.
