Pellets cause less waste but mine were always much more eager to eat the crumbles. The bantams would sometimes start to starve themselves foraging during times of year that weren't ideal rather than eat the pellets. Pellets became last resort food despite having the same ingredients and they would eat the slightly smaller rabbit pellets quite happily. Since it was also harder to get pellets (nearby feed store does not carry them) I just fed them crumbles. The waste was not that high. Vermin were far more of an issue and they sure didn't care if we had pellets, crumbles, or some feed that got wet and dried in to a solid block.
A year or so ago I had some troubles with aggression in the flock I had then. One poor little hen was on her way to getting picked to death. One of the things I learned in researching ways to turn things around was that offering pellets over crumbles made it possible for the hens to eat more in a shorter amount of time. This left them time to get into trouble.
I did quite a few different things to change the dynamic, and one of them was to switch to crumbles. They're busier at the feed trough, and that leaves them less time to find mischief.
I'm glad your production is increasing; that's great! But I thought it bore mentioning in case you start to see some picking.

We have tried crumbles and mash and we have found the crumbles to be the way to go. Never bothered with pellets.
As far as TSC, any feed I've ever compared is at least a buck a bag higher than our regular sources.
