What do I feed after Chick Starter?

[maclady]

Ok-new to chickens and only have 4. My girls have been eating Purina Start & Grow so far. Still on the same 50lb bag but almost done. They will be 12 wks on Wed 5/11. What do I put them on next? Flock raiser and then supplement oyster shells when they start to lay? Or go straight to Layer? Obviously a bag of feed lasts quite awhile here and don't like to waste stuff. I have been using Purina products so far cause they are easier for me to find. Any input would be appreciated. Thank you.

It says on the bag under directions to feed until 4 weeks before laying switch to Layena, so I would buy another 50 lb bag. The second bag should be used up more quickly than the first one since they are bigger.

Start and Grow (Purina) bag says just fine for the first 18 weeks. It illustrates it on the bar graph on the back of the bag as well. I feed Start and Grow until I switch to layer feed. When they start "squatting" and are close to laying, I switch over. Run a mix until the Start & Grow is gone. Just what I do and no problems to date with each batch.
