When should I give my pullets this?

[sparker96]

I purchased this egg boost from my feed store. I'd given them the chick boost as well. Unfortunately, this has very few instructions. At what age should I give them this boost? I have 3 Leghorns and 2 ameracaunas and they are all roughly 9 weeks of age.

Thanks in advance, backyard buddies!

I'd probably wait till laying age. That would be 10 to 18 weeks from now.
There's no calcium in it so you could feed now.

Patience is a virtue. And I want it now!!!
