I have 9 White Leghorns, free range, they are 25 weeks old. I've heard that these birds are good at making nests other than in their coop, but there is nothing in our yard. I've put golf balls in, that hasn't worked. I'm new to the chicken thing and when i purchased them they said they would be ready a month ago. I'm going to be selling half because i ready to move some chicks in and the coop will be over crowded. Do I need a rooster? Do i need more space? (we have a 4X5) They are feed layer, isn't that what the need? What do i have to do to make my girls happy?
