My poults and chicks are separated. All of my chicks get broiler starter whether they are broilers or not which is 22-23%. It makes the non-broiler cockerels meatier also. I feed my poults 30% turkey starter. My 9-10 week olds I have been cutting their feed and feeding half 30% starter and half 20% pellets to get them used to pellets. In a week or so I will move them to only pellets and start introducing a little corn.I have chickens and turkeys together and feed everyone turkey starter when I have poults. Free feed soaked/fermented.
Later all flock if I can get it. Last winter I ended up feeding layer for a couple months.
If no babies or broody I put food out 2x a day
I have been feeding the royal palm tom about double what we feed each adult chicken and he seems good with that. He doesn't leave any feed on the ground. So that should do him fine in addition to grazing all day. I can't leave out a feeder because of my goats. They eat all the things. Including my hydrangea and all of my Rose of Sharon.
