Froglets developing well

My tadpoles are developing at different rates.  Some are froglets, whilst much bigger tadpoles have no front legs yet.

I hope that they survive the newts, grass snakes and foxes in my garden when they are set free to fend for themselves.  They had cooked chicken breast for dinner yesterday and raw liver for lunch today.
Note the two insect larvae hanging on the surface of the water.  The bats can have the mosquitoes if the frogs don't eat the larvae.
