I have a 3 year old goose ("Edith") that has been sitting on infertile/dead eggs for a couple of months. She proved last year to be an excellent mother with goslings we put under her (because her eggs were infertile then too). I just hatched 6 healthy ducklings last week. I have been told it would be okay to put the ducklings under mama goose seeing as she is broody & obviously waiting for some babies. My question is, how old should the ducklings be when I put them with her? They are under heat right now & I'm worried one will get squashed under mama goose. Also, there is another female goose (1 yr. old, "Pringlez") out there with her (it's mama goose's "daughter";unrelated). She has no experience raising babies & is a bit of a mama's girl. I'm worried Pringlez might bully the ducklings out of jealousy or for some other reason!?!? Pringlez has been sitting on a few eggs too but isn't so serious about it. She spends most of her time out & about with the gander. She is grouchy at the moment & hisses at me. I have had geese attack ducks before so I am just concerned. I plan to keep the mama goose & ducklings separate from my gander ("inglez") & Pringlez until they get used to the idea of the babies being there. I just need to know how old the babies should be?!?!? Any helpful information is welcome. Thank you! P.S. It is quite warm out at the moment. It is supposed to be around 80 degrees fahrenheit for the next few days. The run where I plan to keep them with mama goose is located inside of our greenhouse so quite hot in there where her nest is.
