Bengalise Finch flock eating lettuce

My flock of Bengalise Finch with a quick view of Silverbills, Gouldian and Parrot Finch. They love lettuce. It's not very nutritious for them so they don't get it often, just as a treat now and again. But like us, they prefer foods that aren't that healthy 😆
(All my birds get spring greens everyday, which are a lot more nutritious and much better for them, and amazingly are very cheap. Less than a quid for a big bag that lasts me a whole week 🥳)
