Oh yes, I hatch. I haven't used my incubator in a few years, but have some broody girls that I've used to hatch some bought Ameraucana eggs or eggs from my own flock. A few years ago the broodys had an unplanned hatch that resulted in all cockerals. That was a big pain getting rid of extras. I kept one beautiful blue Ameraucana boys out of the batch. What happened is I went out of town and DH didn't collect the eggs all week and one of Am hens went broody. I found her sitting on a ton of eggs. I candled and there was about 7 or so already developing. I teased DH that they were his babies.
You do know that I have Dels? In fact they are my main breed. I have chicks ordered from Paul Harter to increase the weight of my birds. I like my Dels and they are good layers. I'm setting the incu with more eggs so I can switch out the old girl. My only real complaint and I expect anyone who lives in the colder states is the frost bite. I'm still working on the humidity thing to see if I can prevent it. I've done the vaseline and bag balm but haven't had much success. I think it's something you have to do every night.
