I have a question regarding what and when to feed them other things other than the store bought "layer" feed. My girls are about 3 1/2 months old and curious as to when I can feed them other things. I was giving them a worm here and there as I was gardening the woman at the feed store said I probably shouldn't yet. They just started on Layer feed and sometimes I throw in their cracked wheat and grit. My question is when can I start giving them extra things? For example I have some spinach that bolted so I was thinking of giving it to the chickens? What does everyone feed their chickens at this age? Thanks so much!
