I got my 3 chicks as pullets in July. I don't know how old they were, but I'm guessing about 8 weeks. Here's my barred rock, Blueberry, with my 4 year old granddaughter a couple of weeks ago. Since then she (Blueberry) has started to develop wattles and her comb is getting a little bigger. Does this mean she's getting close to laying eggs? If my estimates are right, she's between 18 and 20 weeks old. What are my chances of having some fresh eggs for the holidays?
