I've been raising free-range laying chickens for many years and I've always been disappointed with their productivity. I've tried just about everything to make them lay well. They live a stress free life with access to a large amount of pasture during the day. I feed them gmo-free, locally grown feed and during the winter I give them supplemented light. They aren't overcrowded, they have access to grit, dust baths and I treat them monthly for mites, lice and worms. I use ISA browns, which are the one of the most productive breeds, but still I don't get nearly enough eggs. I have 100 birds now and I'm only getting 10-18 eggs a day! There production is on and off all year. Some weeks they'll lay 50 eggs a day and others they'll 5. This really doesn't work well for me because I have multiple restaurants, a bakery, a co-op, and dedicated customers counting on an exact number of eggs each week. They're starting to get frustrated and I'm afraid I'll lose their business if my chickens don't become more reliable. I've contacted Cornell Extension and even their experts had no idea why my chickens aren't laying well. This isn't the first bad batch either. The three flocks before this one were just as bad and over the years I've tried barred rocks, sex links, Austrolorps and speckled sussex from different hatcheries. Nothing seams to work well. Please let me know if you have any solutions. On the upside, I have a smaller flock of laying ducks which I'm really happy with. About 75% of them lay a large egg every day. They're much easier to raise, they have many less health issues, they eat much less feed, they get along better, their eggs are bigger, they forage more and I enjoy watching them waddling around the pasture. Most of my duck egg customers don't taste a difference between them and chicken eggs, they're better for baking and I've read that they have more nutritional value. I'd be happy to only raise ducks, but I feel like my chicken egg customers wouldn't be into the idea. If you have experience selling duck eggs, let me know how people reacted and how you market them. Thanks!
