Well, we called it quits on chicken. It's just too difficult to do a trial when it's a battle to get Kara to eat the food. We have now moved on to our apple re-trial, a food that she is much more likely to eat.
So far there has been nothing out of the ordinary. She's has it about 3 or 4 times now. I'd like to think that if it was going to cause a problem, that we would have seen that problem by now, but we will continue with the trial for the 14 day total. She is loving having apple back in her diet. She has gotten quite sick of potato and sweet potato and doesn't seem to "yike" (like) anything lately! I just hope that apple continues to like her!
