Is There Such a Thing As To Many Greens?

[OldGuy43]

I doubled the amount of greens (Romaine) that I gave them yesterday, and they went through it even faster. Should I give them more? They're not quite 3 weeks old.

There's nothing wrong with greens but you still want them to be getting a minimum of 18% protein from all intake.

I don't feed anything but a high protein grower at that age unless they're free ranging.
I let them out as weather permits but they get no treats till they're at least 15 weeks.

Grower has optimum nutrition for healthy growth. Be careful of tampering with that nutritional balance.
I'll sometimes give yogurt or mealworms but that's all.
