Looking for some help - don't know if these are ducklings or goslings - our daughter wanted to add them to the farm so we purchased them, but the man we got them from doesn't know what they are either. Right now they have been adopted by our momma hen even though they are over twice the sized of the chicks - they haven't gotten any feathers yet and they love grass and clover!! We would like to know what they are - ducks? geese? breed? and if the sex can be determined by color? Thanks!
