its not really down to a moulting mix
with the price of corn nowadays its hard enough to even be worring and thinking about
personally ill be mixing my own corn for the moulting season
50% beans new as i feel new beans are better than 2yr old beans
30 % wheat
15 % rape seed
5 % linseed
all mixed together feeding the birds as much as they want in a trough
also malasas in the water as this is a good form of calcium
they will also get vita pro in the water and as many baths as they want
this is only me though
hope this helps
