A housing order for all poultry and captive birds in the country is in effect from today, due to the high risk from avian influenza - or bird flu.
The Department of Agriculture announced the measure last week.
It comes after confirmation of two bird flu outbreaks on separate commercial turkey farms last week.
On Tuesday cases of the virus were detected on a farm in Carlow, while on Wednesday another outbreak was confirmed in a flock on a farm near Kells, Co Meath.
Three kilometre protection zones and 10km surveillance zones are in place around both sites.
The outbreak in Carlow was the first on a commercial poultry farm in Ireland in more than two years.
Since Thursday a housing order has also been in place in Northern Ireland, where two bird flu outbreaks on separate poultry farms were confirmed on Friday.
Following laboratory testing, cases of the Highly Pathogenic Avian Influenza (HPAI) H5N1 strain were confirmed on the sites in counties Fermanagh and Tyrone.
