While malpositioned can take longer, I start an assist after 24 hours. Many times I can't complete because the veining toward the bottom is still active, but I at least start it and go as far as I can.
Should be fine as long as it's not dropping significantly. Malpositioned often do fine on their own, though they make take a little more time to progress. You should give it 24 hours at least before starting an assist unless it seems to be in distress.
Hi! :welcome
They are ok in the incubator for a while. Some people don't even take them out until the hatch is done. A good share of people wait until they are dry and move them. I move mine as they become active in the incubator. I won't leave a strong healthy chick in the incubator more than...
For incubation or hatch? During incubation if you are not in a high elevation I recommend starting with a low humidity to begin with. Around 30-35%. During the late spring summer, I can usually achieve this dry. When we have lower, dry humidity in the house I add a wet sponge. For 2 1/2 years...
Ok, humidity that high will most certainly drown them. The 9300 is notorious for the display being off. First, I would suggest, if you don't already, to have your own checked thermometers and hygrometer in the bator, or at least check the bator's thermometer display against a known accurate...
That's my question. Please tell me that is just your hatch humidity. If that was your humidity the whole time, then there's your cause of death.
What kind of incubator are you using, is it forced air or still and what temps are you averaging? Have you ever checked your thermometers/hygrometer...
For chickens I consider normal hatching process from external pip to zip roughly 24 hours.
I do assist. If there's no progress by 24 hours I will start an assist, but to be honest, many times I don't go very far because they still have veining, which is most likely why they haven't progressed on...
