I would echo John's comments about "rate of lay" being only one of many things to consider when putting your breeding program and pens together. It was 3-4yrs ago or so that I was experiencing 6mos or more of no eggs from my Ameraucanas. Since I'm in this for the Exhibition and it's a hobby, and I'm not running an egg business, and I usually wind up way in the RED, I sucked up the cost and just worked with it. I've dealt with small eggs, torpedo-shaped eggs, very light blue eggs, and even white eggs. In fact, it was those white eggs that actually increased my production and bettered the size and shape because those 2 BW hens gave me 5 eggs/wk each.
Now I honestly can't tell ya what the birds are producing because I haven't kept track of that - yet. It's been pretty low on my list of priorities but it is climbing. All I know is that I'm getting more eggs now, quite a few that are going 2oz and better, and I'm getting the best color on some I've ever had. Oh, and no more of those stupid, tall, thin, torpedo-shaped eggs either.
So why do I bring all that up? Just to say this... my advice is to look at your birds and set your priorities. You can't fix everything at once. Er, I should say I've never been able to fix everything at once. I've had to decide what I wanted to fix and realize that it might take 2-3yrs to get it fixed and set. Close your flock, define your lines according to your goals, and then work toward them. Maybe you'll wanna start one line just to see if you can increase egg production, size, color, shape, or what-have-you and not worry about the SOP. Nothing wrong with that.
I also wanted to agree with Mike about BYC. Though I wouldn't even take BYC as a grain of salt. There's more misinformation and outright falsehoods on there than any other poultry site I've seen. At least there was and that's why I haven't been there in years.
