Yes — kale is a calcium-rich leafy green and a better daily choice than spinach, especially for laying hens.
Keeper's noteClip a whole leaf to the cage bars — shredding it is half the fun. Massaging the leaf first (like for a salad) softens it for smaller beaks.
Why kale is good for parrots
Kale delivers calcium, vitamin K, and vitamin A with far less oxalate than spinach, meaning the calcium actually gets absorbed. For egg-laying hens and growing chicks, that distinction matters; for everyone else it's simply one of the most nutritious greens available.
How to serve it
Wash well; serve whole leaves clipped to bars or chopped into chop.
Raw is best; a quick steam softens it for picky birds.
