I am new and going to my first buy/sell/trade meet up at the local feed store. I have some silkies babies to sell that will be a month old by then. I was wondering what a reasonable fee would be for one month old birds (just pet quality) and also if I needed to bring anything like small boxes to give people or will they have their own containers? Also, anything I should know about buying other birds from people, like what to look for/what to avoid. Any advice is appreciated. Thank you.
