They will both most likely lay a pale green egg. Mom (DC) lays a pale brown egg, and I assume Dad has genes for Blue eggs. Some of their older 'siblings' hatched by my co-broodies are laying - and are laying anywhere from a deep olive to a lighter green. (They all had the same Dad, but different Moms, the pale green egg layer's mom was an Astralorp, which lays an egg just a hair darker brown than the DC girls. So, most likely Eli & Babs will lay pale green egg like hers, but could be a light brown, too.
