Mae Gorchymyn Lletya hefyd wedi'i gyflwyno ledled Cymru a Phrydain Fawr sy'n golygu bod yn rhaid i bob aderyn a gedwir gael ei letya mewn adeilad addas, fel sied neu adeilad allanol, neu strwythur dros dro.
A Housing Order has also been introduced across Wales and Great Britain which means all kept birds must be housed in a suitable building, such as a shed or outbuilding, or a temporary structure.
