Depend on if the chicken is laying or not.
The easiest thing to do is just offer a starter/ grower and offer Oyster Shells on the side.
I believe that you were asking about a Breeder feed and feeding it year round, most good breeder feed still has a good bit of added calcium but not as much as a layer feed.
Example -
Buckeye Layer/ Breeder
Crude Protein, min. 18.00%
Lysine, min. 0.85%
Methionine, min 0.38%
Crude Fat, min. 3.50%
Crude Fiber, max. 4.50%
Calcium, min. 2.70%
Calcium, max. 3.70%
Phosphorus, min. 0.65%
Salt, min. 0.10%
Salt, max. 0.60%
Vitamin E, min. 18 IU/lb
A better alternative would be Buckeye Big 4
Crude Protein, min. 20.00%
Lysine, min. 1.10%
Methionine, min 0.39%
Crude Fat, min. 3.50%
Crude Fiber, max. 4.00%
Calcium, min. 0.70%
Calcium, max. 1.20%
Phosphorus, min. 0.65%
Salt, min. 0.10%
Salt, max. 0.60%
If you want a Purina product you could go with Purina Game Bird Flight Conditioner which also has the animal protein that they should have in there diet,
Crude Protein, not less than 19.0%
Crude Fiber, not less than 12.0%
Crude Fat, not more than 2.0%
Lysine, not less than 0.8%
Methionine, not less than 0.3%
Calcium, not less than 0.85%
Calcium, not more than 1.35%
Phosphorus, not less than 0.8%
Salt, not less than 0.35%
Salt, not more than 0.85%
All feeds listed contain animal protein.

Be careful with Purina Flight Conditioner. I bought a bag in June & it had no animal protein. My feed store told me they took it out of all game bird feed. I don't know if they really did. I know my bag had none listed. Email Purina & find out first, otherwise it's no better than Flockraiser.
