Name/Sex that chick!!!!!

Some are 10 weeks, some 8 weeks and a few (not pictured) 4 weeks. We have a RIR, Australorp(2), Cornish cross (oooppps),Brahma(nicest chicken of all), Black Silkie, SWEET Banty Nanking Rooster, Buff O, A deceased black sex link (predator=Bloodhound puppy), Ameracauna(probably EE), and a Barred rock. What are these?
#1 The left pullet-what breed is she?I put her next to the Buff Orpinton to show her redness, however she was a yellow chick unlke my Rhode Island red???? She is lighter than my RIR and has some creamy spots. Is she a sex link? I did not think I got one of those! Any other ideas?


#2 Australrp possibly roo next to? Maybe a younger two weeks pullett australorp or black sex link or banty??????(those australorps always have bright red wattles and red combs, even the hens). I was supposed to have only one of each. (So now three australorps?) Will he (if he is a he) hurt my Banty rooster with 10 hens? I put them out with the roo at 6 weeks. (he is nice). What age does the spur come in???


The third is a little baby australorp, hopefully pullet.

 

The BA roo is a real turkey. He is tough to catch and stands in front of the hens... to gaurd them. Drives me nuts!!!!! I certainly do not want two of those turkeys...........ooopps I suppose that is politically incorrrect... I will call them chickens even though they act like turkeys. When does the spur develop?
