That's a good link from Slack, Brenda......
I'm in the Midlands and my daughter's in Devon.....her spawn arrived much earlier than mine and developed into tadpoles earlier too.....
However, my tadpoles became froglets much earlier.....hers had yet to develop when we spoke a week ago....
Other years it's the other way around because Devon is warmer....so maybe just a funny year but your friend still has time....hope so.....a pond full of froglets is lovely....x
