I had to have my three week old chick put down today.I originally suspected and the vet agreed that she had two slipped tendons. I agreed to let them do a necroscopy. Afterwards I started thinking about her eyes - they were a greyish color and she seemed to have a hard time seeing food unless it was large or dropped in front of her so it created a vibration. She couldn't walk - both legs were folded underneath. She had started off with pasty butt. I'm starting to worry that she may have had Marek's but I'm not sure - the necroscopy should tell. However, I have two other chicks inside the house (where she was) and eight adults outside. If Marek's is possible where should I go from here? The other chicks are very healthy. Thanks for the help!
