I have 400 chickens laying eggs that I sell at the farmers markets.
Chicks--be sure to get all CHICK feed, starter etc. The feed store and back of the bag will easily tell you want to feed. Chicks need to eat at least 5 times a day up to 6 weeks, 4 up to 8 weeks, and about 3 times a day after.
I keep open chick filled feeders in all troughs when raising young. I don't raise them any more, I buy 16 week old pullets that are close to laying from another local farmer. Easier for me in time and cost.
I go thru 2,000 to 2,300 lbs of bulk feed every 5 weeks.
best of luck on the chicks!
