Im new here as well, and had never heard of lockdown, and i still odnt entirely understand what it is. I am hatching guineas at the moment too. I have a styrofoam incubator, and I have never taken the turner out, except for a second to add water. They seem to be hatching perfectly fine with the turner in it as well. And as soon as the keets are dry i remove them from the incubator and into the brooder they go, unless there is more than one at a time them i leave them longer until they are all dry.
Is it bad that mine are hatching sporatically? I had a few hatch 3 or 4 days ago and then i had one hatch two days ago and two more this morning. All seem perfectly healthy, and i had a few more hatch as well, but two died. One was weak and i think another may have accedentally cracked his egg or he tried hatching too early, and then another one was very lethargic and just passed away of unknown causes. I think im doing pretty good though considering i have 6 in the brooder right now. And I have chicken eggs in the same incubator due for the 21st of may. Is that bad? The guinea eggs were being brooded by a hen at first but i decided to remove them from her because i did not want them running loose everywhere for my dog to catch and eat.
Luckily the temp in my incubator is steady, but i think yours will be fine just so long as you are able to make the temp steady. Are u from GA? (looking at username) I am too, and if your keets dont hatch i can sell you some of mine as I was planning on selling them anyways.
