A very dear friend of mine lost her home to a house fire this past week. She and her family of 4 teenagers (she has 6 total, but 2 are adults) are now picking up the pieces and trying to move on. Before the fire, she had asked me to take her 5 Isa Brown hens because she no longer (after 2 years) had time to take care of them properly. She has recently opened her own restaurant and is rarely at home anymore...she even has 3 of her kids working for her. My question is this. These 5 hens are 2 years old and have consistently layed 4-5 eggs per day YEAR ROUND...even here in Michigan. How much longer will these hens continue to lay this well? I was expecting them to slow down at 2 years...am I right?
