I am on day 29 with my duck eggs...there is no activity. I candled them this morning and there is no movement. I candled them on day 20 and they were looking beautiful! What happened???!!! How much longer should I give them. I think I am already smelling stink from the incubator. I am sooooo disappointed. I stopped turning them for lock down Friday December 27, that would have been day 25 ....was that too early. I am becoming really sad writing this.....:-( any advice....?
