These two are definately Mille Fleur D'uccle
Pic 1 - i would guess is a white cochin it does not appear to have the right shape or size
Pic 2 - Definately a Porcelain D'uccle
The other 3 could be golden necks maybe but i have not seen golden neck chicks with black before. If you call your TSC you can ask them which supplier they used for chicks this year, they should be able ot give you the hatchery name/s. For instance michigan used privet and townline this year. After you find out the hatchery or hatcheries they used you can figure out what was offered that can help a ton to narrow down exactly what you ended up with. If you find out some back and let us know and we should be able to identify your breeds or give a good guess anyhow.
You definately have atleast 3 d'uccles though.
