Oats with propionic acid?

[peafowl_Lover]

Hi, I'm wondering if oats with propionic acid added to them are safe for hens, as they are so cheap compared to the single bags of oats without propionic acid. Is this safe for my hens?

Can you contact the manufacturer and ask them. Propionic acid is used as an animal feed preservative but I don't know what concentrates are safe for what animals, what is in those oats, why they are so cheap, or if those oats are supposed to be mixed with something else before they are fed. Too many questions for me to have an opinion.
