He can,,,,,, but long term,,, he would be getting too much calcium in his diet. Ideal for non laying chickens is 2%calcium.
Layer is about 4% calcium. It is challenging to feed one bird separately, and with different feed, but not impossible.
Your other option, and one taken by many, including myself is this;
I feed all my chickens (I have only hens) a 2% calcium Alflock feed. My hens vary in age, and some are not laying regularly anymore. I offer Cracked Oyster Shells free-choice. The laying hens supplement their calcium needs by choosing to snack on the oyster shell at will. My chickens also get some of their calcium needs in the green grass/weeds they consume while free-ranging in my backyard lawn.
