1. It seems like when I turn the eggs, the doggone things wanna roll. Is it a big issue as long as they are moved around three or so times a day? 2. I don't know that any of our chickens have ever had the Mareks vaccine. We are still new to this. We bought all of our chickens from Tractor Supply as a few day old babies, so I "assume" they were vaccinated, but what about our week and a half olds? Do we HAVE to vaccinate? Our chickens stay in a coop, and can't range because of wild animals. Is it too late to vaccinate the new ones? What do I do with the ones due to hatch next week? Thanks again, ya'll are great!
