Joan J here too!
It's their first full year, and next year will need a bit of thinning out, as they're crowding each other...
Plenty of feed makes a huge difference, as does plenty of water when it matters. I had a few Glen Moy left over, and just chucked them in as well, and they'll need a haircut as well, but they're finished just about.
... Forgot to agree with Mum, the birds don't seem to worry about them at this time of year, presumably because there's too much else to peck!
