Farmers protesting outside Aldi and Lidl in Cavan town have apologised to customers who are now facing empty shelves inside the supermarket.
It comes as the protest - organised by IFA - enters its sixth day as farmers and food producers seek a 2c increase per egg by the supermarket.
IFA Poultry Vice Chair Brendan Soden said egg producers in the region are now facing closure because of the failure of the stores to give a fair return to farmers.
He added that it was a damming indictment on the stores that local farmers were faced with having to take such action in the first instance.
Protesters say they are staying put until they get results and even hinted at similar action taking place in the south of Ireland before this week is out.
