I really see very little difference in the bearded versus the non-bearded silkies. Just one more little poof under the chin. Not even really noticeable. I never paid attention to mine before. They are all little fluff balls. I wasn't aware I had a silkie egg in there. I had found a nest of eggs and put them in the bator cause they were small pullet eggs and I didn't know how old they were for sure.
I have GQF incubators. I have 2 that are incubators, One that is a hatcher, and 1 that can be used in combination. Plus I have two styrofoam bators which I use when I run out of room in the spring. I usually use them for quail and pheasants because the eggs are smaller and I can get more in. I pulled 6 chicks out of the incubator this morning. The black cochins and the black silkies look very similar other than the number of toes. I may have some mixes of the two as well.
It's taken a lot of time to get good at hatching. I didn't start out that well. I just finally got the right combination going.
