I dont need my meat birds to be organic....But as close to it as possible would be nice. Hatchery states I should feed regular chick feed thats medicated for the first 3 weeks and then to swtich to a broiler feed till butcher which should be between 7-9 weeks. So my questions are... 1. Is the right? 2. Should I feed them regular medicated chick starter for 3 weeks? 3. How long with the medication stay in their system? Really dont want to eat medicated birds. 4. Is 22-23% high enough? Thats all my feed store has. Thanks.
