The 'Union of Poultrymen of Ukraine' has reported a 10% decrease in chicken egg prices in November, attributed to an increase in supply. However, prices may fluctuate based on market conditions. The previous price increase in September-October was due to rising production costs and unprofitability in the sector. Factors such as energy supply interruptions, increased production costs, and the impact of the 'grain agreement' have also impacted egg pricing.
