I am new to chickens. We have an Easter Egger & a Buff Orpington who are about 23 weeks old. We adopted a hen who turned out to be a bantam judging on her size & the eggs she started laying 2 months ago when we finally got our coop done! Lately she has laid a few eggs that are a darker brown than all the others and have faint tiny white flecks. I got one of each today. But I noticed the all the darker brown ones are slightly bigger than hers, but not what I would call normal full sized eggs. My Buff has started investigating the nesting boxes in the last week or so bit I don't see her sitting in there like I do the bantam. Could these eggs be from my Buff??
