I personally do not feed the high powered feed to mine. The layer feed and grower feed specially formulated for chickens is about 16% protein, not 22%. The higher percent protein is meant for game birds. It also is good if you are mixing it with other stuff that cuts their overall protein intake down, closer to where it should be. It is all about how much protein they eat every day, not about percentages. They will eat more food in the winter to get enough calories to stay warm, so that is an especially bad time to feed a higher protein feed. In the summer, they will eat less total volume so upping the protein in the feed is not such a bad idea, especially if they are getting more stuff that is low in protein.
Some people believe that the 16% is the minimum that the commercial operations can get away with, so that is what they use. I disagree. The 16% is the most efficient they have come up with to get the egg production they want in the egg size they want and to maintain the chicken's health. When I get my blood work from my check-up, the results are checked to see if they are in a certain range. A few things have either maximum high's or minimum lows, but most need to be in a range of highs and lows. Too much of a good thing can be harmful. Their body has to work extra hard to get rid of the excess protein, the stuff they don't need. It is not that they are going to fall over dead the instant they eat the higher protein feed. It is not that they are all going to be harmed. But the effects are gradual, building up over time in some of them, a lot like growing chicks eating too much calcium. Those effects are not immediate and will not affect all of them the same way, but over time, with a consistently high intake of calcium, it has been proven that growing chicks can develop bone and liver problems. Not that all of them do and not that they immediately have problems, but they can and many do.
This is my opinion and I know a lot of people disagree. I don't know what else you are feeding yours, but I truly believe that if the feed is the majority of their diet, your chickens will be healthier if you follow the recommendations based the research done by a lot of major universities.
Good luck however you decide.
