We have three 21 week old (on Thurs) white leghorn/rhode island red crosses. They've been with us for about two weeks in our chicken tractor. We've never had chickens before! They aren't laying at all and kick the straw out of the nesting box. I thought leghorns were early layers. The box is on the ground of the house part of the tractor. Is that ok? Is it possible that they might be molting? I keep seeing large wing feathers on the ground and the brown one's head feathers seem to be falling out on one side. Can they molt before laying? I can't find answers in the books-hopefully someone can advise me-maybe we're doing this all wrong!! Thanks!
