I’m so lost with what to feed my girl’s. I have 7 RIR and 8 Barr Rocks. Both Groups are almost 5 months old. Currently I have them on grow/finisher food. In the last week, eggs have appeared. Maybe 1 a day. Some have very soft shells. Here’s my question, I purchased Purina Layer food. Do I wait until more birds are laying and then change over or just feed everyone the Layer food. I don’t want to start to early and affect there future laying abilities.
