If all your pullets looked like this sweet little girl you'd probably have interest if she was truly bantam sized.
The roo has pretty tail color but I'm not a fan of seeing Leghorns LF or bantams with droopy wings - obviously showing other than Leghorn characteristic to me but I think something that can be corrected by following Mr. Honour's breeding input.
Look through the previous posted photos in this thread on the bantam Buff Leghorns to get a feel for what the bantam Buff Leg breeders are striving for. There are a few bantam breeders with excellent input and they are very kind to help.
