i have a few questions. I am getting Cornish x. 100 of them! I see people free feed for 12 days, then its 12 on 12 off, right? so for the 12 on I free feed? I have also heard of some that say feed in the am, and the evening but let them get hungry between. which is preferred? trying to figure out how to guage how much they need in the feeders and to make sure I have big enough feeders for them!
