Your feed may or may not be a factor. A few things to keep in mind, and pardon if you already know all this, but these are good to be aware of....
1. Check the mill dates on the bags always when purchasing, every brand will mark in a different way, some stamp on the sewn on label, some stamp on the sewn seam on the bottom of the bag. Always buy the freshest you can.
2. There is no way of knowing how your bag of feed was stored and handled between the time it left the mill and you buying it. I have seen pallets of bags of feed sitting in the pouring rain getting soaked. I have purchased bags that were spoiled or beginning to spoil. Always check for anything off in how it looks or smells. A very strong chemical smell, odd colors like gray or green or white, or clumping could be spoilage. I always empty my bag into another storage bin so I can see all of it before feeding. If anything is off I either take it back or toss it (find out what the return policy is where you purchase). Not worth losing birds to bad feed. Sometimes a bag that has gotten wet or sat in water will be spoiling from the bottom and it's not obvious until you get deep enough in the bag. I actually smell the bag seams in the store to make sure there is no strong odor before buying, I'm sure some people think I'm nuts.
3. Whole grain feeds in some cases can cause health problems since some birds will pick out and eat only the parts they like and leave the rest. Most chickens love corn, and will choose that exclusively over other ingredients. If you are finding a lot of feed on the ground they may be doing that, digging for the parts they like, and feed on the ground can become moldy. A crumble or pelleted feed reduces the digging and picking and choosing of the parts they like.
None of those things may be an issue in this case, but did want to bring them up.
