Just make sure the feed they eat before leaving for the day is a complete feed designed for any sex of chicken (no extra calcium) and it offers at least 18% protein. Keep the OS out and check it regularly as you don't want it to get down to just powder.This is all great information on feed, i am fairly new to raising chickens, i give mine meal worms and scratch as treats, but they are free ranged, so i would appreciate any information on free range chickens feed, i also give mine protein pellets, but they only eat it when first coming out of coop in am, then they fly out and seem to prefer free ranging
I have a flock of 24 and I use mixed bird seed for scratch. I throw out 3 small handfuls of seed to get them out of my way when I clean the poop boards in the morning. They come back into the coop for a small handful of raisins that I doll out by hand. Each bird gets 2-3 raisins. That is the extent of their treats.
I feed a can of tuna 3x a week during the molt. It is mixed into their bowl of fermented 22% broiler mash. That is always gone when I lock up at night and there is a little bit of 18% crumble left in their troughs. That holds them over in the morning on the rare occasion they are up before I am out to fill the feeders and release them from their run into their 1/3 acre pen to roam for the day.
