Treat's age, tofu, frozen, ect?

[Lovesilkty21]

When’s the right age to start treats(we get day olds chicks a week from today Thursday) and I was thinking some scrambled egg as it’s what they came from and should help boost them a bit for the first or second week

And will chicken’s eat tofu?

What is your chickens Favorite treat(s)?

If frozen veggie’s what kind or mixed ect.( I live in AZ where it’s billion a good part of the year so I like to know about treats that can help cool if anyone has ideas too)?

Thanks so much
