This will be interesting to see how their relationship develops.
We had our very first broody setting on 8 eggs this spring and she hatched out 6 healthy chicks. Watching her mother them has been amazing!
The first day,or two, as they were hatching under her body, I believe she really didn't move off of the nest at all. Then she began walking over to the feed and water and "teaching" them to eat and drink. Tehy are a little over a week old now and they are definitely a "unit" mother and babies are NEVER far apart.
Let us know what your momma does over these next couple of days! The fact that she is not pecking them to death has got to be a good sign!!!
