If she is allergic to wheat, It would be best to not have wheat sprouts or chaff available, and that includes in the chicken feed, when she's likely to be in the coop, or handling birds that have wheat on their feathers. Likewise the barley and rye. There should be feeds available if you look (I hope!). Otherwise, at least she should always wear a good face mask out there so she's not inhaling offending grain dust. Then it also depends on just how reactive she is to the stuff, and what else is on her list. Other grasses? Completely allergy tested for other environmental triggers? Meds and allergy shots do help, I know. Mary
