Congrats.... they are Awesome

I hope ya'll made it through the storm, we watched your light show from our front porch, from our view it was great.
I got a question, it's probably been asked before, if so sorry for the repeat I must have missed the 1st.
As most of you know I sell my LF eggs for eating. just to help with the feed bill. I have had to drop my prices due to the small sz my girls are giving me. I thought I did a good job of picking all Lg egg layers. All my girls are young and the BJG and the ISA's have been laying for a month now and still I get tiny eggs from them, the only lg eggs I am getting is from my older BYM girls, and they don't lay every day, They are at that age of maybe 3 eggs a week eh. My EE's that have only been laying about 2 weeks have stopped and so have 2 of my Red Sexlink's, I have not changed feed or housing. I know the snake threw everyone for a loop but I haven't see it for 3 days now. I can half understand the ones that have stopped laying ( 10 in all ) due to the snake, maybe they just aren't relaxed yet. But the Small egg thing is not making my customers or me very happy. We all have been waiting on the egg sz to get better and I have dropped my prices by .50c trying to be fair and keep my customers. If this keeps up much longer I will have to buy adult birds and I have NO LUCK at all with that!!! and it is too late in the year to start chicks of a different breed.
Did I pick bad egg laying breeds? Am I doing something wrong, not giving them something something they need??? Please if anyone can help me out here I would be forever in their debt.
I feed: Purina All flock pellets, with a side of free choice oyster and grit. and Scratch once a day for like a treat. Plus plenty of veggies from the garden, and the neighbor gives them veggies and table scrap's as well.
The breeds I have laying right now, ( if you want to call it that ) : BJG small egg, Wellies small egg, ISA's small egg, a few of my LT. Brahmas small eggs, Red Sexlinks have stopped laying, EE's have stopped laying, BR have stopped laying.
What on earth is going on??????? I'm down to 10 eggs a day and 9 of them are Small.
