We have two call ducks, Bonnie and Clyde that we've had for about a year now. Bonnie recently laid about 10 eggs in a week and a half (she really gets down to it when we feed her peas, haha) and we put them all in a bucket that had a heating pad on the bottom. We put a small bowl of water in it and covered it with a towel to try and maintain some humidity (we weren't very prepared, as you can tell). They were in that for about a week. The first egg that was in that was candled and found to have nothing in it. So now we have nine in this new incubator we made using these guidelines: http://www.cyberquail.com/incubators.html They've been in that for maybe two weeks. We haven't candled any of the rest. I wasn't here when my sister did the first one, but I'm not sure if she really knew how (I don't really, either, tips?). But my question is, the incubator was above an air conditioning vent, which we didn't realize. So the temperature almost constantly fluctuated between 98.4 degrees and 104 degrees. So I'm pretty sure that would have killed the eggs, right? We figured that out though, and moved it to where there's no vents around and now it's holding steady at 98.4 and 20% humidity (does the humidity need to be higher?). We have holes punched in it and we cover/uncover holes with duct tape to try and control the temperature, so I covered one of the holes a little to try and raise the temp to 99.5. I am going to try and candle the eggs that are in there soon (once I find a flashlight and I'm sure that I know what I'm looking for) but I'm pretty sure that there's not going to be anything in there. But Bonnie's outside with a little egg butt going on, so I think, once we get the incubator more steady, we'll try and get her to lay those eggs and start with a new batch. So what do you guys think I should do? This is our first go at hatching some eggs, if you can't tell. Note: Bonnie will sit on the eggs for 4-5 hours, but then she'll get off of them like she's bored and never go back to them. I read that call ducks are supposed to be good mothers, but I don't think Bonnie has a very strong mothering instinct. What do you guys think? General question: Do the number of duck eggs in the incubator affect the temperature of the incubator? I would think that more eggs would raise the temperature, what do you think?
