layer pellets vs breeder pellets

My flock needs more protein (broken feathers, pecking and feather eating). The layer pellets are 16% protein, but I can get breeder pellets with 20% protein. They seem to have comparable calcium percentage (4-ish percent).  We hope to hatch some of the eggs, but not a large quantity. All 28 hens and 2 roosters are on the same feed and they get scratch every once in a while as a treat.  Is there any reason why I can't switch the entire flock over to the 20% protein breeder pellets permanently?

Detali, oh yea! They have plenty of space! We have 28 hens and 2 roosters.  Their coop is 8' x 12' (96 sq ft), which is 3.2 sq ft per chicken. Yes, that is lower than the 4 sq ft per chicken, but we live in Southern California and are outside during the day year 'round. They only go in the coop to sleep and lay eggs.  In addition, their is a second coop that is used as the brooder coop or just a "getaway" during the non-winter months (too draft for winter so we close it). It is an additional 20 sq. ft.  As for the run, it is 24 x 24 if we close up the brooder coop and run access (a little less than 20 sq ft per chicken).  With the brooder run open (even with coop closed) it is an additional 8' x 24', which increases it almost 26 sq. ft per chicken.  Not to mention, that if we are home (most every day since DH is unemployed), their run is opened and they free-range (we live in 0.41 acre). 

The ingredients are very similar aside from higher protein.  We don't ship out eggs or chicks, but we do hatch our own.  I will switch over to the breeder pellets then. Thanks all!!
