Hi there,
We have a Partridge Cochin, Little Miss Muffet, and she is extremely good a t brooding ( this being her first time), she has been sitting on eggs since feb 11 and she will only leave the nest once a day to stretch her legs, for 20 or so minutes. She however has not been a great mother, yesterday she squished one of her newly hatched babies to death, at least that is what we think happened, the baby was flat when we found it under her.
I also heard that Silkies are really good brooders.
