Mysterious puddles

I've found 3 rather large puddles in the shed- one on one occasion, two on another.
I put it down to two things; Tigger since she has been near them on the floor when I've been in, or hard rain as its been raining all afternoon.

But of course two things go against these theories. There are huge amounts of water and I don't think buns could wee that much, they've both gone straight back to being toilet trained, and also it doesn't smell like wee, or anything! Pretty sure it'd pong. No colour either when I wipe it up. Had a feel around the shed roof near the puddles but can't see or feel any wet patches.

Hmmm.

Hmmmm does sound like a leak.

How is she doing?

Its just so strange! Will see if there's anymore at tea time.

I went in two times earlier and I'm certain she was having a small nibble on the pellets from last night caught her doing it twice.
When I left she was nibbling hay and she had this adorable face on her looking at me as if to say 'see mum? Proud?'

Thanks for asking Katie

Found a fourth puddle.
Still no smell and the roof feels and looks bone dry! I'm very confused
