I apparently have big problems in my incubators None of my eggs are hatching. . In my Brinsea I have lavender silkie eggs and in new Hova Bator are lavender ameraucana eggs I bought. Almost all of them started developing fine, but then some of the silkie embryos died around day 9 or 10 of development or on day 18 or just before pip. . Several I helped hatch--one lived for a week but had leg problems. Not one of my lavender silkies has llived. The ameraucana eggs started developing fine but about 5 days ago I noticed the air pocket in some of them was way too large for the develpment stage. In some there was movement. Today is hatch day, and no movement in any of them and in some the air space is in the small end. This is so heartbreaking. I have been hatching eggs for years and have never had this kind of loss. Have tried to keep the humidity between 50-60 percent and the temp on both as close to 99.5 as I can get them. Does anyone have any suggestions. The lavender are from my own flock and I give them grain, greens to eat -- put vitamins and probiotics, ACV in their water.
