As the title states, I wonder if it will affect her? We have 2 LARGE tubs of PB that expired last year, and since they are high in protein we wanted to feed it to the chickens stuck in with the seeds or on veggie leftovers.................our allergist doesn't know about how it will affect it. By any chance, does anyone have knowledge of this or where to find info? I don't even know what to Google! In other words, will the chickens' consumption of all that peanut butter somehow transfer into the eggs we eat or that she'll eat in crepes? She has an epi-pen, so I guess if I don't know for sure we'll just toss the PB. Not a huge deal Thx!
