On number one.....I have SLW and she was something like your ADORABLE little chick.....There are a couple similarities between your unknown chick (#1) and my SLW....The wings are very similar but the yellow neck is different and the combs are the same....Keep in mind though I have seen TWO SLW PULLETS that look almost identical to her so I am going to follow my gut and say SLW PULLET. Keep in mind that most SLW look like the on in this link.....
1. ROOSTER
2. ROOSTER
3. ROOSTER
4. PULLET
5. ROOSTER
6. PULLET
GOOD LUCK
P.S.
THEY ARE ALL GORGEOUS NO MATTER WHAT SEX OR BREED!
