UPDATE: Yesterday was hatch day (day 21) and I found that another egg had gone missing! However this time there was evidence, there was dried on yolk on 3 out of the 4 remaining eggs but there were no shells or any other evidence. Last night around dark I couldn't resist and I decided to examine the remaining eggs.
One I found had a circular spot of cracking like what you would see when you go to crack an egg to eat, and a line crack coming off of it. The other 3 showed no signs of cracking that I could see.
This morning when I was doing coop chores one of my other hens flew up onto the nest with the mom (Now named Momma Patty). At first, she was just clinging to the edge and pecking at the bedding in the front. Then she reaches over to the back of Momma Patty and started pecking there. At that point, I had had enough and kicked her out of the coop.
I am not sure that she was going for the eggs but I think it could be likely. I am not sure that the cracked egg was cracked because of a hatching chick I think it is likely that it was the other hen or a lack of bedding maybe. Momma Patty does not seem to like having a lot of bedding under her. I use nesting pads made of a fake straw mat I buy them on
amazon. Momma Patty tore through the nesting pad in the box on the very first day when she was making her nest and threw most of it out onto the floor. Every time I check on her I try to add more bedding but it is almost all gone or pushed to the sides by the time I get back to her.
This morning there were no signs of progress that I could see.
A thought has just now occurred to me, was it bad for me to mess with the eggs yesterday if they are close to hatch. I have read a little bit about shrinkwrapping when the humidity changes in an incubator near hatch time. Could this happen when I take the eggs out from under her? I do know that Momma Patty was off her nest around 4:30 pm yesterday... Do broody hens stop getting off their nests when hatching is starting, say to avoid humidity and temperature changes to the egg? She is a first-time momma, however.
When do you think it would be a good idea to abandon the eggs? I was thinking that if they don't end up hatching I could get a few chicks from my local feed store to put under her. Should I try candling the eggs again... I was thinking I might tomorrow night if there are still no signs of progress but again is it bad to handle/turn the eggs if the chick is ready to hatch?
Thanks so much for reading, BYC is always my first stop for any chicken questions I have. Any advice is extremely appreciated.
