Sebastopols can look pretty naked after the breeding season.
Mine all look very ratty right now and are starting to molt.
They won't be in prime feather until this fall.
If their goslings are from this year they will need time to fluff out too. Don't judge any of them right now.
Wait until this fall-winter and as for the 2009 golsings, they will improve by their 2010 molt (if they're going to).
Austin good description of how they sound.
You can breed curly breasted to curly breasted.
I have done it exclusively until this year with no problems.
Supposedly you can decrease twisted wing tip (not to be confused with angel wing)
by breeding smooth to curly
but I haven't been at it long enough to know what the percentage rate is.
If any Sebastopol looks "dirty" its because they don't have clean bathing water and/or live in filthy conditions.
Mine look sparkling white year round because they get fresh water to bath in on a regular basis.
