Hello, so this issue needs to be solved immediately before my birds finish their food. I have 11 two month old chicks, and I ran out of food. I asked my friend to get some food for me, I even told them the brand and they didn't get the right one. This was starter crumble, so I didn't feel comfortable using it. Also, these are all 50lb bags we're talking about. So, I asked my other friend who has chickens to get the food I wanted, and again, this person didn't get the right feed! This time it was layer crumble, but I don't know if they're old enough yet? Also, I have 2 roos. Now, they only have a tiny bit of feed left, and I checked the feed store and they didn't have the feed I needed! What should I use, the starter crumble or the layer crumble?
