I have a flock of 9...1 Barred Rock cockerel and 2 Barred Rock pullets that are 23 weeks old, and 6 Commercial Black pullets that are 19 weeks old. My first to lay was Sansa, one of my CB's. She was 16 weeks old (1 day before she turned 17 weeks old) when she popped out her first egg. Second to lay was Boring Girl, one of my BR's. She laid four days after Sansa at 21 weeks old. Since then, someone else is laying, but I'm not sure who...I'm thinking it's Athena, my other BR, because her eggs are bigger than the other eggs, and it's the same color as Boring Girl's eggs, and they are both BRs. Sansa lays an egg every morning, as does Boring Girl...but she didn't lay one day out of the past 3 weeks. Athena (if it's her) lays sporadically...I've only gotten two eggs from her in the past week. Over the past 3 weeks since they began to lay, I've found 3 soft eggs. One was in a nesting box, the other two right under the roost on the coop floor. I hadn't been giving them oyster shell then, but I started smashing up egg shells and giving that instead. Then last week I bought a bag of layer feed, and have been mixing it with the chick start I still have, but also giving them smashed egg shells. So I figure it's not lack of calcium, but kinks in the new to laying system that need to be worked out. This morning I went to open the run door, and I found two soft shelled eggs OUTSIDE the run. I let my chicks free range from 6 p.m. until they put themselves to bed, usually around 8:30 p.m. So these eggs had to have been laid last night, right? I mean, something couldn't have dragged them out of the coop and not eaten them? The yolks of both eggs were still intact. If something took the eggs from the coop, they would have eaten them. Which leads me to believe they were laid between 6 and 8:30 p.m. last night. But why? I know that's a silly question, but I don't understand why one or two of the girls would lay soft shelled eggs outside the run that late at night. My other girls only lay in the mornings. Do chickens lay in the evening as well? Also, who laid the eggs? One of my currently laying hens? But they laid eggs yesterday morning, so that would mean two more eggs for them in the same day. Was it one or two of my other girls who laid their first eggs, but since they are brand spanking new, their egg laying system is out of whack? Theories, please!! And why are they soft if they are getting calcium in their feed, as well as egg shells?
