I've been feeding Maili and Annie a raw diet since last Thursday. They've been getting 2 drumsticks a day with an egg every other day and some salmon oil. They were looking fantastic, they were super shiny and healthy. Small firm poops and everything. Today I get home from work and see that the back half of Annie is covered in hives and Maili has them on her neck and behind her ears. Could they BOTH be allergic to the raw chicken? They've been eating chicken meal in their Taste of The Wild kibble their whole lives and have never broken out like this. I've used cooked chicken during training class with both of them and they were fine.
Could it be something else? I'm freaking out because I don't want to keep feeding them raw chicken if they're going to break out and Annie has a conformation show this weekend and she looks awful

BTW they're not itchy at all, just bumpy.
