DD1 names the chicks. At least with ours there has always been at least some little difference between them. As they age the differences increase. It helps that we get only 2 or 3 of a given breed in a batch we order. I expect it would be harder if you got a dozen of the same breed (or as in the case of Sex Links and Easter Eggers, non breeds
).
I would advise you to not name them based on what they sound like as chicks. "Peep" (2012 Cubalaya) should have been named "Sqwark". And Trill (2017 Barnevelder) should have been named "Nasal Honk". Well maybe not THAT but that is what she sounds like now, certainly no trill to her voice any more. None of the other birds were named after their sound, the EEs have always been named after Greek goddesses of mythology. Andromeda, Persephone, Eos, Athena, Penelope, Cassiopeia.
