i can offer
12 mixed eggs from my laying flock(all kinds of hens..with two RIR roosters and 1 Buff Orpington Rooster)
or
6 New Hampeshire Red Banatm eggs
or
6 golden laced cochin bantam and silkie cross eggs(more than likely to get pure)
No Idea I don't even know if they are SQ. I bought them from an auction as chicks.They are nice looking though. Except my roo gets beat up by the gueines.
