Re layer food, since Two Crows has kindly moved the immediate emergency question to the best forum.....The healthiest my flock ever was when I had a mixture of little chicks, roosters, and hens. I couldn't possibly buy different chicken foods for them and keep them from eating out of each other's food pans, and I didn't have the time or space for separate coops. My chicks were raised in a pen out with the flock from day one, so they were fully integrated with the flock by the time they were 4 weeks old.
So I switched to feeding either All Flock or Grower, whichever was on sale since the nearest feed store was 50 miles one way on a two way road and I didn't want to make that trip more than once. I fed oyster shell free choice on the side. Never had an issue with eggs that had weak shells, never had a health problem in them, and they were strong, active, and their overall condition and production reflected the slightly higher protein content. Just for future reference....
