That's nuts! I do know that information in your advertisements will help. The last lady who bought chicks from me said that she had never heard of them before, just checked my ad out of curiosity and did further research after reading the part of my ad saying that they were the size of a bumble bee at the time. A very quick blurb about them, general information and pictures would probably sell them more quickly. I also make sure that I advertise EVERYTHING when I make an ad. If I have ducks hatching out that I'm trying to sell, I make an ad for them, but make sure that I also add whatever else I'm going to have available in the future into the ad. Interest in the ducks can draw interest to your buttons, or whatever. That's the beautiful thing about internet advertising, you can use impulse buying to your advantage, WITHOUT harming the animals. They'll see how adorable the buttons are, then they'll be so excited about them that they'll spend the next few hours researching them. It sure beats petstores, where they see, they ask four or five questions, then they come home and research later, AFTER buying the pets. I don't delete my ads either. I post "SOLD" after the title. That way everyone can still see my information, and know to get ahold of me before the next round is sold out.
Of course, I have yet to have any massive hatches. My hatches have all been smaller batches or I've kept some of them as breeding stock. So, the flames may die down once I start hatching larger batches on a regular basis. I'll let you know on that one, I have two or three batches of about 20 in the incubator (one set in the hatcher actually).
