Hey there, thanks for reaching out, and good on you for keeping close watch.
At 35 hours post external pip, you’re right to be paying attention, especially if there hasn’t been much progress and the membrane still wasn’t breached.
The darkening around the pip hole can sometimes be a sign of drying membrane or reduced circulation, which can be dangerous if left too long.
Here’s what I’d gently suggest:
1, Candling (with a small flashlight) over the pip area can sometimes help show you if the blood vessels in the membrane have receded. If they’re still bright red, it’s not ready. If they’re faded or gone, intervention may be okay.
2. Humidity is key right now,you might want to carefully apply a bit of coconut oil or sterile saline to the exposed membrane to keep it soft if it’s drying out.
3. If you do assist, go slow - only peel a little at a time. The goal is to help the duckling do what it would, not to rush it out if it's not ready.
4. And when you come to it listen for movement or peeping - that’s a good sign it still has strength.
****Assisted hatches can be successful, but timing is key. If the membrane looks white and papery, or sticky and dark, intervention might be necessary. If you’re unsure, better to stop than go too far.
Let us know how it’s going. You're doing the right thing by checking in. I'm sure other people will head into this one and help you with some more advice.
Wishing your little one a safe hatch!
