Last spring (2017), I got 2 cuckoo maran chicks. They were both just a few days old when I got them. At a few wks old, I noticed that Paisley was smaller than Poppy, but didn't think it was a big deal. Poppy started laying eggs around 20 wks, but Paisley has yet to lay a single egg! She's not the brightest bulb in the box and kind of trails behind the flock doing her own thing. Her crown and wattle are way darker than my other hens, almost maroon. Is it possible that a hen can never lay an egg? Can I feed her anything to possibly start her producing?
