Mapping Your Chicken Feed Program

Best Results
Feed Purina Start & Grow continuously as the sole ration from hatch until laying age (18-20 weeks). Or for a flock of various types of poultry, feed Purina Flock Raiser free-choice until laying age. At 18-20 weeks of age, feed Purina Layena free-choice. Be sure to gradually transition from one feed to the next. Always provide shelter and a constant supply of fresh, clean water. Consumption will vary depending upon season of the year, nutritional needs of the animals and availability of other foods.

Caution
Store in a dry, well-ventilated area free from rodents and insects. Never use moldy or insect-infested feed.

Important
A feeding program is only as effective as the management practices. Actual results can vary depending upon feed intake, environmental conditions and the quality of management practices.
