My incubator is full at the moment but when its empty, I plan on taking it to work (a nursing home) and setting it up there for our residents to enjoy. I thought it would be fun to have a variety of different things hatching for them to enjoy. I was going to set chicken eggs and now that I have buttons I thought "wow wouldn't the residents love that" and I could set them 5 days later so they would all be set to hatch on the same day. Would the size difference be too much for a safe hatch? I could also set the quail only 4 days after the chickens so they are up and running before the chicks hatch and be able to get out of teh way? This is my hope but if it is too risky for the buttons I will just hatch chickens.
