Oh no, the silverlaced wyndotte may have jumped into the pen. I hope not! I'll post some pics in a week time..cute chicks. sorry to hear about hatch problems, but yes, dry conditions have a lot to do with poor hatches IMO. but then i incubate everything and then give the new chicks to the broody of my choice, if i trust her. LOL
as for the chicks, barred would have a white spot on the head, so no i don't think any are. as for the black/self blue (lavender) there is no way to tell if a black is carrying self blue, unless one parent was s.b., or produces s.b. when bred to another that carries or is s.b...
as for the lighter chicks, i had several like the bottom one in the bottom pic, they were silver laced. but unless you have silver laced in your mix i honestly wouldn't know what it is.
