Hi everyone, I had a couple of questions and concerns that I am hoping some of you may be able to identify. About a week ago I received an order of chicks in the mail from Cackle Hatchery, there were 36 of them. On Friday, I noticed one of the dominique chicks couldn't use one of her legs, I seperated her, with two blue cochin chicks as "friends" for her. This morning she passed away. Then, I looked in the brooder and spotted a Delaware chick, with the same thing. Both chicks are holding their leg at a 45 degree angle from there body, refusing to move it, they fall over a lot and have trouble moving easily. At first I though they may have just broken a toe, however I am beginning to suspect Marek's. i did not take the blue cochin chicks out because I figured that they had already been exposed and I did not want to spread it more so in the main brooder. We had all of the chicks vaccinated against Marek's, so some of my questions were: 1. Can I help the chick that possibly has Marek's survive? Or are the symptoms already to far progressed? 2. The Blue cochin chicks who I put the with the first chick are healthy and thriving still, will it spread to them? Can they be put back in the main brooder or will they be carriers and dangerous to the other chicks? (I never would have put them in with the sick chick if I knew it could be marek's) 3. A couple of the chicks in the brooder were hatched a week before we got our mail order, and they were hatched in a home brooder, therefore, they were not vaccinated, should I remove this group of five chicks? 4. I have been helping the sick chick eat/drink every couple hours by giving her a mixture of hard boiled egg yolk, and a probiotic/vitamin/electrolyte/mineral mix dissolved in water. 5. What else could cause something like this? I haven't seem any other symptoms of Marek's in the either of the two chicks that got sick/impaired so I can't really soldify my suspicion. Thanks in advance for any advice!
