Fertilized eggs???

[Sheily Gonzalez]

My chicken has become broody the last week and today I checked the eggs and on some of them you can see little veins but on others I can’t tell how can you tell 100% because I feel like there are too many eggs for her to take care of and I also don’t have enough space to take care of all of the eggs that may hatch.

Time will tell which are fertile and which will thrive. I currently have a hen that's raising 20 chicks, so... don't concern yourself on her ability.

Post pictures of the candling. If she has been on them for a week, fertile eggs will certainly start to develop.
