I have wk old chicks. I have some broilers and some pullets. I started them on Purina Start and Grow a week ago. I am now going to put them all on Purina Flock Raiser. Is this ok? I have been told also to limit feeding times for the broilers. Is this necessary? They are all housed together and would like to continue to keep them all together if possible. Any advise on feeding my little flock would be great. I also have one rooster and 7 layers which all eat Purina Layena and are free range part of the day. I try and keep them confined until all have laid each day. I also need to try and keep them all out of my gardens. Again, any help would be wonderful. Thanks ahead of time.
