When to switch to layer feed?

[NewBostonChick]

Hello all.. We got our 1st egg today! Yeah! It was soft and had a hole in it, perhaps from the hen scratching.. My question is the girls are still on grower cal mash along with the 2 roosters..(that were supposed to be girls.. ) If I switch to layer feed, what about the roosters eating the layer feed? Thanks so much.. I am a new chicken lady..

You can safely switch to layer feed at 18 to 20 weeks, or when you get your first egg; whichever comes first.
The roos can eat the layer feed right along with the hens.

The added calcium is very hard on their kidneys. Best to feed them grower feed or starter grower at least until they are 18 weeks old.​
