Wow. Never knew that. I always thought of molting as the crazy feather filled run all the sudden when their older. That’s what I like about BYC... learning something newJuvenile molts are the ones they have as they grow from chickhood.
From the first set of feathers you see in the first 6 weeks that push the down out,
then one or two more before onset of lay(I seriously don't know if they grow 2 or 3 sets of feathers in this time)<scratcheshead>
Then the first full adult molt at about 18 months.
But sometimes a bird between ~7-12 months will have a partial molt their first fall/winter.
