When exactly to switch over to a laying feed?

I’ve been introducing all flock 20% nutrena to their grower starter from nutrena 16% with oyster shell on the side. I’m transitioning them all over to all flock since I will be purchasing ducks in the spring. My 2/12 ladies are laying (20 week EE and 1, 30 week buff orphington lol...) I have some pullets who are also about 15 weeks (2 black copper Marans, 1 isa brown and 1 silver laced wynadotte).
Their eggs have been rock solid and nearly impossible to crack. I mean very pleased with their quality.

Wow, that hard! Thanks for sharing info about your feed. I will look into it. I am using Purina start and grow and was planning to switch to their Layer feed if needed.
