That's a lot of change (birds in and out) plus brooding birds don't resume laying for a few weeks after being broken.OP I'm in the same situation of sorts. All I can figure is too much change so the girls are just being defiant. lol
3wks ago we got 15 eggs in one day. We sold 5 of our hens.
Since then egg production has dropped to 4; maybe a day. We usually get 4 yesterday we got 6 or 7; thought things were doing better. Today we might only have 3!!
We should be getting around 10 eggs a day. (More since I've found out that's not molt but probably roo damage on the feathers.) Only have 1 who's being allowed to brood.
But we broke 2 others from brooding; I've yet to see one of them if not both lay since then! O.O
I'm at a loss other than selling the 5 hens stressed them on top of moving flocks around at night to the coop. (Having to add the geese & ducklings to the coop.)
And now their run is split some so the 9weekers can have space. lol So I guess it's just stress...all up in arms over things. lol Even though they're being fed well & taking care of. Smh.
