I've had my BO setting on eggs her first time. On day 17 she up and decided that she was done with it! So fortunately (?) I had another hen that had been broody for a few days and I stuck her on the nest. Tomorrow is day 20. Don't know if mama #1 was off the nest too long for the eggs to hatch, it could have been a few hours & they were cold. So if they do hatch, will mama #2 be okay with them after only 4-5 days of setting? The other concern that I have is that she is a Welsummer and I have read a lot about them being awful mothers. Anyone have any experience with this situation or Welsummer mothers? I'm getting really nervous!
