I had the same problem. They would develop to day 18-19 and would never hatch. I have NO IDEA what that problem was. All of the sudden they started to hatch just like the rest of my eggs. I am going to chalk that up to pullet eggs.....I started setting Lav X Lave eggs about five months ago. I was having really bad hatching rates, only one or two chicks per setting of 18ish eggs at a time. This last time i set 18 and had 11 hatch
. Like a lot of the others I was seeing development clear into the last couple of days and then they just would'nt hatch
. The only change I made with this hatch was using the dry hatch method and using distilled water in the hatcher at lock down. I was setting other eggs at the same time and was getting a pretty good hatch on all the other breeds but not the Lavs. I will try another dry hatch in a month or two and see if I can repeat the hatch rate.
Did you trim your birds even though they are ameraucanas. Some of the top breeders trim them just to make sure the fertility is close to 100%. I am sure someone will give you some other pointers on feeding them some extra quality feed to help you also plus worming and treating for coccidious, plus extra vitamins and electrolytes in the water. I've used Rooster Booster on a very old male once that had poor fertility and it worked for me.
. At least I am pretty sure that's what she told me....
