Had to cull our little chick, We tried antibiotics, wonder dust, vitamins, gatorade and time. She had a tumor like thing growing on back of her neck that was getting larger. She was struggling to breathe, and just not thriving. I hate this part, only 3 weeks old. I am blessed that the other 26 are healthy and thriving. I suppose it does not get easier has we have to make this choice for our birds. Gotta love my DH.
