Do you leave your humidity the same for chicks too? What kind of incubator do you have? I’m just trying to see what everyone does with their eggs so I kinda have a good feel. It’s good to know they will hatch at the time they should…I’m sure they’re maybe an early bird here or there but average is good. I’m gonna talk to my Call lady when I go pick some up from her next week. We bought a lock for the door today so this whole mess can’t happen again unless I do it. I’m honestly thinking that I might vaccinate all of them when this second batch hatch. I will just have to be mindful of Marek’s possibly spreading to them through my shoes and cloths. I wish the vaccine can be used 22-22 days after the first use…I get an occasional chick or duckling that hatches a little early but almost all hatch on time, regardless of size. The early hatches come from eggs I left in the nest and collected a large batch at once. Guessing those eggs are having some unseeable development happening even with no hen brooding them....either from the hens warming them as they lay more or from our high temps. When I was using my homemade incubator it was harder to keep the temp exact...with it I got more early hatches from temps running high. Those are the only things I've seen effect time required to hatch.
I can't swear with call ducks because I haven't hatched many yet...but my bantam eggs I can swear...mine take the normal amount of time. So far my duck eggs have also.
I don't change temps or humidity for lockdown. I stick to 99.5 and 55 through out. I have an excellent hatch rate and almost never lose a chick during hatch. I know reading says bump the humidity, but I never will. I tried it in the early days and had worse luck then I do now.I stick to what's working for me.
I worried more about the calls too. I read so much about their hatching problems! Hard not to worry. I'm guessing those pet quality beaks are the difference. So far mine are almost all hatching well on their own. I had one hatch with a deformed beak that needed assistance, one hatched that would spin in circles every so often from the moment it could stand also needed help hatching, and a malposition that I thought would need help but made it out on its own. Since you also have pet quality, I'm betting almost all will hatch well on their own.
O that's too bad...I'm so sorry for your loss. I'd time it so the maximum number possible get the vaccine at the correct time.
