You said you only have 2 hens. If I read the first post right you have 1/2 a 50# bag of food left. How old is that food. I have 18-24 hens at a time and they would't consider eating food that was over 4-6 weeks old, but then they go through a 50# bag in 1-2 weeks, dependng on the number of bugs they can scratch up.
A 50# bag of food is wayyyyyyyy to large a bag for 2 hens to eat with in 2 months time. ( 2 months is a good time limit for food for chickens, after that it gets stale and they don't like it). Try a smaller bag of fresh food.
Also, I make Wine and when I made my Jalapeno Wine the smell was more than strong. I had just opened a new bag of cat food a few days before. My cat would not touch it after I started that wine. Had to buy her a new bag. Chickens liked it though (they were molting at the time).
Try a new bag of food and toss the old if they go bonkers on the new. Crumbles or Pellets, your choice not theirs.
