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.
so I am not certain what is normal eating behavior for them, but it is my amature understanding that they do need some calcium, just way less than laying birds who need lots of calcium. I'm sure others know more.
