I have two BBS marans hens that are laying mostly non-fertile eggs, even though they are in a pen with two roos and a total of six hens with those two roos. Those two slackers are pullets that are just starting to lay and the roo is a young cockerel (July) just starting his first season. These girls are larger and narrower backed, and the blue one is more of a bronc and the splash one is cooperative. The roo seems like he is a good roo doing a good job, so I will have to just keep on keeping on until they figure it out. It stinks to have a bator full of great looking eggs and then pull half of them a week later for non-fertility. I don't want to eat them after they have cooked for a week in the bator. I wonder if I could boil them and feed them back to the girls? Anyone know why this would be a bad idea? The are lighter colored eggs, but they are XL, even though they are newly started laying pullet eggs. At this rate they will be laying emu eggs by next year!
