The Spawn Dilemma ("frogs are my canaries" obsession#n)

What shall I do about the spawn? This time last year, our fishpool was a heaving mass of amorous frogs, but none of their spawn survived. Most wasn't fertile, maybe some succumbed to a March cold snap. Many individuals seemed very stressed (reddish skin, skeletal thin) though I didn't see any definite signs of the "red leg" disease. This year, let us say the over-population problem seems to have been resolved. There's one mating pair in the fishpool, nothing going on in the new small pool, and I have two batches of spawn. The first laid is fertile: I have commas indoors and creased oblong eggs outside.
I think I'll bring the whole of the first lot indoors, leave the second lot outside, see how that works.
