Maybe you'll finally get some blue eggs! I haven't had blue eggs in 7 years, I miss them so much!
We have blue egg layers. You may have a couple of you wish. However, I cannot guarantee that they will lay in the egg boxes; our blue egg laying hens like to play “where did I hide the nest that you might accidentally step on months worth cache of hidden eggs on the middle of a 90° afternoon, hehe”.
Strangely the babies that are now laying sage eggs have been using the nest box. Sadly I cannot offer you them for they are doing at least half of their jobs.
