FBB, Chicken Pellets and Growmore?

Wow I had no idea there was so much chemistry to it    :blink:
I've just been chucking on our homemade compost every year (which includes the poop & bedding from our henhouse), adding a bit of extra compost made from our local food recycling centre if I need any more.  I try to rotate as well, but sometimes the planning gets a bit lost & confused! (went wrong last year when distracted by sprogs & mucked up the rotation - grrrr!)
Things seem to grow ok, but I guess I'm lucky(-ish!) cos I have clay which is I think quite full of nutrients.
However, I'm not entering any competitions
