The RSPCA’s new standards for pullets must be met by Wednesday 5 December (unless otherwise stated by the standard).

Aviary rearing systems will be permitted to help better prepare pullets to navigate multi-tier systems in lay.

Please note that any multi-tier aviary rearing system must be accepted for use by the RSPCA prior to certification.

To find out whether a system is accepted for use by the RSPCA, please contact the RSPCA's farm animals department.

Other changes include:

• A requirement for ramps for all multi-tier systems - research suggests this results in better bird mobility, strength and cognitive ability
• Increased raised perch requirements to better match provision in lay

• An amended ‘protection from other animals’ section to reflect changes to the law on rodenticide use.

Copies of all changes to the standards and guidance have been sent to relevant RSPCA Assured members.

The review process, which is undertaken in consultation with the farming industry, veterinary profession and welfare research sector, is necessary to ensure that the standards take proper account of the latest scientific research, veterinary knowledge, and practical developments, and therefore continue to represent ‘best practice’ in farm animal care.
