Hi Karen- yes BYC is a great place for information and I TOTALLY agree with you- chickens are a blast- the eggs are just the icing on the cake.
In answer to a couple of your questions:
Apple Cider Vinegar (raw unfiltered) is a great way to boost the beneficial bacteria in their digestive system- but I doubt it would have any effect on their pecking. I agree with another poster about not feeding laying pellets for the younger ones- they need feed for growth still. Also on the space- 4X8 is way too small for 25 chickens if they are confined in there for more than sleeping. Although it sounds like the first batch did fine with it, which is curious -but they do have a nice large run, is the run shared by both sets of birds- all 50? If so, it may be that even though the older girls didn't bother the younger ones-the fact that the older, more dominant birds are in there- it has put stress on them and they are re-establishing their pecking order in a very aggressive way. Although I think you said they were doing it before you moved them, so you you may have a couple of " really bad bulllies" in there- you might want to observe them to see who is the culprit and doing the most pecking- then cull them, in addition to giving the younger girls their own run if possible.
As someone else said- it really does help to give them something to do- like pecking on a "flock block" (for that many girls you may need more than one so they won't fight over it and dominate it)- but it does encourage more natural pecking behavior, and is supposed to stop inner-flock pecking. You can also tie up lots of fresh greens and hang them up so the girls have to stretch and reach for it- that keeps them occupied and adds additional nutrition to their diet. That's all I can think of for now, hopefully more people will have some more ideas for you.
As far as the sex links not laying- they may be going into their first molt, and although I wouldn't expect them all to do it at the same time, they can stop laying for up to 3 months while their systems recover from their whole first year of laying eggs. It helps to add more protein again to their diet- to help them since molting is a stress too. Boss (black oiled sunflower seeds), yogurt, cheese, & wheat grass sprouts are a few things that can add more protein.
Keep us posted on what you try- and good luck- I'm sure you'll figure this out and get it straightened out- you sound like an awesome "chicken mom" ha. Post some photos of your flock if you get a chance too- we all love to see each others "feather families"
