I had two 5 month old chickens and two 1.5 month old chicks. Both pairs are a couple. I keep the little ones seperate from the older ones. The older cockerel contracted Marek's. He had a paralysed leg and died two days ago. Now one of the little chicks is showing symptoms of Marek's. He stays standing all day and sleeps while standing. His eyelids keep drooping. His wings are drooping as well. He seems pretty Ill. The other older hen and the other little chick seem fine. I keep my chicks in a big enough bird cage. The cage has no flooring material like pine shavings and their droppings remain open to the air. Should I put a layer of soil in there to cover their droppings. I wash the cage everyday. Older hen's cage: Smaller chicks cage: I feed them chicken feed that looks like this and table scraps mainly rice and spinach. How can I cure my chicks? Is it actually Marek's in little chick or just sleepiness like never before. What should I do to keep my chicks safe from diseases and healthy?
