Countdown is removing eggs sourced from a farm implicated in footage showing dead and rotting hens in their cages.

Animal advocacy activists released the footage of the Waikato colony egg farm yesterday.

It also depicted severely de-feathered hens living in overcrowded conditions.

Today, Countdown has announced it will be taking all eggs sourced from the farm off its shelves, until it can be sure the farm's practices are up to scratch.

Spokesman James Walker says the company is getting in touch with all its egg suppliers to reinforce the importance of complying with the Animal Code of Welfare.
