Thank you all for your advice :).
I now feel happier about not feeding them till April. I didn't know that the water temperature was a factor on when to stop or start feeding, so thanks for that. There is plenty of weed and I notice they are nibbling on that. Maybe it is all a question of where you live and the experience of people in your locality? I live in Torbay which is considerably milder than some places, but even here we had a frost last week severe enough to freeze the pond surface till around mid-day. I was glad of the plastic ball I have floating in the water!
Chloe never feeds and Petmas always feeds, but the concensus seems to be - don't feed in winter, and I think I'll stick with that for the time being.
As to where I went Patricia - I spent just over a month visiting my sister in Calgary, Canada, an English friend who now lives in Colorado, USA and a lass I 'met' playing Scrabble on the internet who lives on a ranch in Wyoming! I had a fabulous time in each location, but particularly in Wyoming, where I saw more wildlife in three days than I've ever seen outside a zoo in my life! We drove round the periphery of Yellowstone National Park, which is not open to vehicles in winter, and saw in large numbers, white-tailed deer, mule deer, longhorned sheep plus a pair of American eagles (up really close). The following day it was moose, antelope and elk - fantastic! I took hundreds of photos with my new digi-camera. Sorry - this is rather off-topic, but you did ask! ;D
