I also have been hatching all of my EO keepers under broody hens as opposed to incubators like I do for my other breeds (the incubator allows me to track who the mother is, but I don't care on the EO's). EO's are my for fun flock and I have enjoyed being able to treat them like a traditional homestead flock and not worrying about color standards.
Are the broody hens EO or another breed you keep as a broody flock?
Thanks,
M
