Glad you are able to get new feed.
Don’t be put off asking for help.
Sometimes people who post really don’t listen and so folk jump to more assertiveness than is always needed. Everyone is just wanting the best for the chickens.

I don’t have a jar to hand right now. The brand is Kaytee I believe and it is formulated for resuscitation of birds.
I learned about it from a person on BYC who is experienced in tube feeding.
It is a powder you mix with water to the right consistency for tube feeding.
Vitamin B is water soluble and very safe - don’t worry about overdosing.
They need it every day and in high doses when they are deficient.
It also degrades rapidly so if feed is old it’s vitamin B will have degraded.
Vitamin B complex is readily available at pharmacies and grocery stores...
