One of my younger girls has started laying and I have no clue as to who it could be. We have 2 EE and a Barred Rock that are likely to be laying any day now, but the (almost) 16 week Brahma is the one that is always in the coop that these eggs were found in. The coop isn't used, but we do put a separate feeder inside to let the smaller birds eat without the bigger birds harassing them. There are Brahma feathers inside the nest, but she climbs on everything (and everyone) that she can find. Her feathers are everywhere. Thoughts on which bird these could belong to?
We also have a female khaki but I assume she'll be laying in the garden instead of a 4' high nest...
