The last two eggs didn't make it either. She collected newer eggs and is still broody on those that were collected. This girl has been brooding since June 17th. I keep water and food in front of her at all times. There are 6 newer eggs now under her. She hasn't left the nest for about 5 days now. I'm waiting for her to stretch her legs so that I can candle these eggs to figure out where we are in the process.
Good luck! Poor girl, some are so determined! Hope you get some good spider veins going on when you get the chance to check.
A lot of people might advise you to break her from her broodiness as long stretches of brooding can put a lot of strain on a hens body, but I recently let a hen sit late on a clutch as she was determined and it's worked out fine. I did as you did and made sure food and water was available all the time.
Hope you get some lovely little fluff butts soon x
