Exchanging our 3 Isa Browns for more long-term laying chickens, and would appreciate people's input on what to get. The Isa Browns haven't laid an egg in over 3mths. Two are over 2 yrs, and even the 3rd, which is around 18mths - 2yrs, is no longer laying! I've since been told that this is common with this breed though, which was deliberately bred that way for the commercial market?? So, we are now looking for good layers to supply eggs for a family of 5 over a longer duration. We live in a hot and humid climate of suburban Australia, and already have a White Leghorn, an Australorp, and two silkies. They all free-range around a very large backyard.
