I picked up 4 mixed variety hens just over three weeks ago. The seller said they all should be laying soon, if not already. I got one tan on the first evening. Next day, got one more tan one. Two days later, one tan one. Nothing else until today. We found 5 tan ones today. They appear to be from the same hen(I may have overlooked the clutch yesterday evening when I checked on them). Anyway, there also appears to have some yoke on a few of the eggs. I'm thinking the hen was egg bound? Not sure at all. Any ideas?
