So I got a question!! Can hens lay eggs without laying mash?? I'm talking about Fertile Eggs. Now I do feed my chickens laying mash but we are out and need to get more. But then again I have a rooster and I was just wondering if fertile eggs can still be hatched without laying mash! One other thing: Can any breed of chicken go broody and if not all can then can ISA Browns go broody?? Thanks in Advance!
