I have some Phoenix that the eggs stop developing after 2 weeks. The last chicks I got are about 6 weeks now and haven't had any since. All are fertile. Could worms cause this to happen? I suspect they have them along with some EE's I have. Worming will happen this weekend but I'm curious if this may be the cause. All my EE eggs have been hatching with no problems with the chicks. This is just my Phoenix.
