We are new in this great hobby and I just finished a book on raising chickens and this book never debated whether throwing feed on the ground for them to eat whenever they want or whether to install feeders whetherr hanging or wall mount. Also, what is the best.....keeping feed available 24-7 or only feed at certain times of the day. We have 5 Buff Orpingtons, 1- Roo and 4 girls. Mainly raising for eggs and fun in our retirement. Thanks for any advice.
