I guess it varies by breed, seems sensical but as you say, strangely undiscussed! I reached out after this first post to some pals with several EEs and it would seem, at least with us 4 chicken buddies, this is a common problem. I had 8 previously, and checking my chicken log for two years...
My EEs last year didn't lay either. I'm trying again with 6 more this year because i like the personalities.
Not sure what's going on with them. Kinda a mutt breed, so i wonder about genetic traits.
I wonder if anyone else has this?
