it's starting to dry up it was an assisted hatch so I was worriedI leave it and it will either fall off or dry out and you can trim it later...no worries
Woohoo! She was just waiting for a speed zip! From nothing to hatched in 5 minutes!! 100% hatch on my 2 Breda eggs - I'll take it
Love it! I had the most beautiful silver colored Breda hatch last night and she stayed curled up in my hand to dry for hours. I will get pics of my two hatchlings and my tiny Blue Orpington who is still amazingly alive though I have had a heck of time getting her to eat or drink at all. She is the same size - maybe even smaller - than the newborns and she is 8 days old. The rest of her hatchmates are outside during the day in the chick playpen. I let her out too but today I am keeping her in to be company for the two newbies. I actually think getting her outside is the reason she is still alive. She didn't finally eat or drink - just stand up sleeping and chirping - until she went out there and saw the big beautiful world and the other chickens.I had a sparkle near my eye and Max tried to eat it.She got my eye lid instead. Oooowwwwwwiieee. I was so mad. She stayed in her bed for awhile, then came out trying to be cute. I still didn't forgive her so she tried helping play soduko on my phone (she is so adorable pecking away at the game) but I wasn't fooled because she loves playing any game on my phone. (She sends texts too but she doesn't know how to spell.) Then she tried cuddling up to me on my pillow and accidentally pooped on it. She gave up and went back to bed.
She's in there all alone. How can I stay mad?
All is forgiven.
For me (we all have our own methods) I snatch it, clip the cord, put some iodine on it and put it either back in to dry or into the brooder - where ever is cleanest and least likely to introduce infection to the cord/naval.
In my experience when I have membrane staining it is the result of the chick trying to pip and hitting a small vein. Then they are still to prevent further damage, they absorb everything if they survived the bleed and then only start hatching again when they are totally done. If it was too big a vein and too much blood then you will eventually know becuase they will bleed out and get no further - in that case there is unfortunately nothing you can do. Its luck of the draw. I have lost several perfect chicks just because their pip happened to hit a major vein
Its so sad. I hope it was a tiny bleed and your smart chick is just healing and waiting to hatch
