I lost 4 of my chicken babies to Mareks, I thought they got vaccinated but they didn't. I am terrified for my new chicks that just hatched. One of them hatched from an egg that could have been layed by a sick hen. I am so sorry for your losses. Mareks is a horrible disease.Was curious how many others on here have dealt with(or are dealing with)Mareks in their flocks. I just lost another chicken a couple hours ago. This is now 13 chickens in total. Did you guys lose ur whole flock? Im so terrified. I dont even get a second to at least try to deal or come to terms with one loss before Im losing another. My heart is so broken I dont even want to have chickens anymore after this.
