I understand feeling stressed! I felt the same way last year when I went through the initial illness. I wonder if you have a cocci out break as well? That is really common when combining flocks. Your birds won't be amune to the strain the new birds carry and vise versa. I would also to treat everyone with corrid.
The other option to consider. Which is a very difficult one. Is culling everyone and starting over with healthy day old chicks. Then be very cautious of ever buying older chickens again. And if you do, make sure you quarantine for 30 days minimum.
