What do you feed your mixed flock since the chicks are still on starter feed. Do you feed the hens starter as well. I have only one hen left of my original 6 with 4 new chicks. The one hen free ranges during the day and I try to put out crushed eggshells for her for a calcium boost that I don’t want the chicks to have. Any other ideas would be most appreciated. The chicks are now 3 months old and pretty “tall” so I don’t feel comfortable putting the eggshells or oysters shells in the run. There is grit. Thanks
