Update on straight cutting frozen hailed canola, and storage questions

Finished combining standing canola in the snow today. Everything yielded better than expected, and quality better also.

First, questions on storing this stuff. The crop was full of flowers, buds green plants and shrivelled frozen seeds, too much of which ended up in the hopper, even with full wind. smells like silage within hours. I just took a truckload out of the first bin that was filled ( just over 10% moisture and 10% green) as it was getting warm already, no damage yet. will turn the whole bin and see what it does then. A couple of other bins are already warming up too after only a week or two, with far less green matter in them, 8 to 9% moisture, and almost no greens but lots of shriveled seeds, again, smells like silage right from the start. Can this be normal to go through a heat then settle down, or do I need to turn everything? I don't normally check bins this soon after filling. I am quite sure I know the answer, wishful thinking right? No aeration bins, but most went into small 14' bins. or 19's but not full. Don't know exact temperatures, just using metal rods.
How dangerous is storing this mixture?

Straight combining was the right choice. There was virtually no shattering in the field, and we had some massive winds too. The dividers shattered a lot depending on the direction. The few swaths I did make in one field (RR) had nearly 50% green seeds over a month later, standing right beside the swaths was under 20% All other fields were much better as low as 2% on most of the Invigor, some RR was also that low.

Header fed really well until it got really wet at nights, when it was impossible to straight cut, tangle wrap, fold over the knife, catch on dividers, but swaths could still be done in the same conditions. Fed the smoothest when it was leaning directly away, tolerably when leaning into the header, if I could cut high enough. Unfortunately, I had to nearly scrape the dirt in many places thanks to the snow, and the deer and moose. Start from south side of fields.

Green stalks will not go through the straw chopper, even with sharp new blades it often bridged on top of chopper. It helped to grind it up more with a tighter concave and faster cylinder. Spent too much time unplugging the straw chopper and walkers, much worse at night when wet.

Some seeds must have kept filling after the frost. Don't know where all of the green seeds went.

Thanks for the replies, that is what I thought. I do intend to market it as soon as possible. Haven't checked yet, but is there a maximum dockage that elevators will accept? The worst of this could be close to half dockage I'm afraid. Small white shrivelled seeds. Is there a limit to how small a seed is considered sound, if they still roll out yellow?
Is there a defined temperature or temperature differential which is safe? Or is it all relative. Could 5C be too high in winter, and 20 be fine in summer?

I checked with the elevator, there is no limit on dockage that they will accept.
Northern Farmer, I've used the charts provided for moisture and temperature, and in a perfect world, I am very safe for both moisture and temp at binning. But with all of the foreign material, that appears to irrelevant.

What I should have asked is:
At what temp does heating starts to occur? so that I don't waste a lot of time turning this sooner than necessary. As of today the warmest core I found is 20C, which I believe is already higher than what it was binned at.
