I am new to raising chickens and have been given 5 hens and 1 rooster that are now six weeks old. Do I give them the grower feed free choose, by that I mean leave it out for them all the time, or do I just put it out certain times of the day. It seems they eat all the time. I want to do what is best for them, I just don't know what is best for them. Thanks for your input.
