Is feed making my chickens sick?

[Schmidt Hill Farm]

Has anyone had any issues with vitamin deficiency or any illnesses related to CO-OP starter grower feed? I have sick chickens and I’m trying to rule out all causes. I had baby chicks get wry neck… once I changed their feed and supplemented vitamins they got better. I didn’t want the feed to go to waste so I mixed it with show flock developer for my older chickens and now they are getting sick. One has wry neck, 2 have dropped wings and one died today.  they all started showing symptoms when I started mixing the starter Grower into their feed. Is it a coincidence or something else. I’m taking the chicken that died to get a narcropsy to find out for sure. They are still eating and drinking and poo looks normal

Could be...
Hopefully you will get the results back from necropsy.

I'll tell you what I would do. IF I suspected the feed was bad, I'd get rid of it - put it in the trash and use whatever feed they were thriving on.

I’ve noticed a change in feed and nutrition over the past two years. It’s been one thing after another. One deficiency and then another.

I had resorted to starting my chicks on game bird feed 30% protein. That worked for two years. Now my birds on game bird feed have started feather eating. Two got splay leg a week after hatching … that says it all to me. This is an issue with nutrition/absorption. This should NEVER be a concern on 30% game bird with electrolyte water every other day.

I had to give them additional vit B and suppliment proteins.
