Growing Hodmedod's

I've been looking at Hodmedods again and, this time, I'm considering the edible seeds they sell. Specifically, Chia, Camelina and Golden Linseed (not Hemp or Coriander).
I had a Chia pet once (if you remember those) but otherwise they're all new to me.

Found this about growing:-
Chia https://www.theguardian.com/environment/...-this-week

Camelina https://plants.usda.gov/plantguide/pdf/pg_casa2.pdf

Linseed https://thelinseedfarm.co.uk/linseed/linseed-faqs

Has anyone grown these? I can't imagine growing a bed of them, just maybe, saving some seeds for my granola. Crushing for oil is a step too far.!!

They might need protecting when ripening, an awful lot of little birds eat seeds. The quinoa I grew this year was attacked by birds a bit and the taste is supposed to put them off: they would eat a bit of quinoa, then have some sweetcorn for pudding. Not too much damage though.

I briefly considered growing a small patch of sunflowers for oil but decided against it when I noted it impossible to save any seeds for next year from the couple of dozen we grow. I think a minimum of couple of acres was recommended by defra to be able to harvest a reasonable percent of the crop.

Coriander same. One year, a row had gone to seed. I went away for a week and when I returned it had all gone.
