Hello, I am new to site, when googling a concern about chickens , that is where I found backyard chickens. I have a daughter that intellectual disabled , and investing in chickens , i thought it would be a good past time for her! We now have 21 chickens , 2 roosters born from first of feb to middle of feb. Most are Dominickers, and they have not started laying? They have a big nice cage, nesting boxes, all the suggested foods. Now winter is coming, and I have heard they is going to delay them?
