The local rehabber just got in 3 black swans who are a little over 3 weeks old. Does anyone know about swans? Do they need to be kept warm like chicks and ducklings? How does one tell the gender? Is it best for them to be in pairs, groups, alone? Thanks for any info. I will also be looking for homes for these guys - will post on the buy/sell/trade board. I'm in OK.
