I did that for my young birds, i fly them two time a day and feed them 1/2 cup for 20 birds. the last fly of the day i feed them a cup. and they have no problem at all. ANdrew
I usually only feed once and that is after the second fly. After the first fly I use just a pinch of small seeds to get them to trap. The reason is after feeding a half ration after the first fly comes the second fly and they won't trap that easy and ignore my calls for them to trap because they are not very hungry. They would want to stay on top of the kit box or the house and want to screw or sun bath. Feeding once a day works for me. My advice to you is to try it both way yourself and see which one works best for you and your birds.
