Our Blue started laying last November and today is still laying and has not stopped in our heatwave. She lays anywhere from 4 eggs/week sometimes up to 6 eggs/week. We feed organic Scratch & Peck layer, extra at-will oyster shell, fresh produce/fruit, organic 3-grain scratch, sprouted greens, organic cooked aromatic brown rices with Brewers Yeast and Rooster Booster added with multi-wormer Rooster Booster for 5 days each month, vitamin supplements, Trader Joe's 0% fat Greek yogurt (22% protein), occasionally cooked shrimp, Friskies all meat catfood, cooked salmon, but never onions, avocado, chocolate, or citrus. I don't know what this heat will do to our Breda's laying as I believe she is due for a molt sometime soon -- she is almost 1[SUP]1/4[/SUP] yrs old. Her first egg was 1.5-oz but her 2nd through current egg is 1.75-oz eggs - pretty bright white. RFR says as the hens get older the eggs get up to large but I'm perfectly content with a 4-lb bird laying medium eggs - I don't want prolapse or eggbound with a smallish hen laying too large an egg for her size.
Note: I just never expected a personality breed to also turn out to be such a decent egg layer too.
