Perfectly normal - it's what I would expect. Last spring it was so cold for so long they had to cram all their 'activity' into a very short spell - this year the weather is milder earlier and this behaviour is perfectly normal.
When I was a child I could hear the noise from the farmyard pond when I was put to bed, and for a week or more it was my excuse for not being able to get to sleep, so '....please can I read for a bit longer?'
Make sure you leave some long grass and plants near to your pond for the froglets to hide in when they first emerge from the pond so they don't all fall prey to crows, cats, herons etc
