If you only have negative ones, that’s okay. Ideally you want to avoid the negative traits, shown in red, and go for the positive ones. This guide won’t go into detail unless it is critical and traits are secondary. The number of successful eggs is somewhat random. To incubate, select the Hatchery and the successful batch. Synthesize another batch of Velociraptors. Select the Hatchery and press on the failed batch to get rid of it, then start another batch.
Once the research is complete, you can try again.
