I've read lots of anecdotes about parents getting upset and rejecting the babies if you apply leg bands.
Of course, apply the leg bands sooner rather than later is much easier. Plus, the adjustment to the band is easier when they're younger.
But I'm scared.
They just rejected a pink-beaked baby and she died as a result.

So that tells me that perhaps they're conscious of the babies' appearance and therefore, could be sensitive to leg bands.
Nobody has leg bands so it's not something they're familiar with.
So what shall I do?
I being stupid and worrying for nothing?
Is it much more difficult to apply them if I wait until they're weaned?? If I do this, I may even find that I don't even need leg bands if they're easy to tell apart. (When I'd purchased them, I had 3 babies. Now I only have 2.)
