My husband goes out to feed the chickens in the morning, and evening, and they are on attack mode when he gets there. I say they must need more food. They are 8-9 weeks old, and on the second kind of food (cant remember, but its a step up from the chickie food) There are ten chickens, do they need like a big feeder and food there ALL day long? Or can you feed them twice a day like this? How much food a day would you say 10 young hens should go thru? And when do they start laying eggs?
