Chase?? you never run from a goose they are all bluff unless they feel they have the upper hand. I had a not so good encounter with geese many years ago and never thought I would have wanted any but I cannot imagine life with out them. [My gander was hatched and raised by a Muscovy so for 5 yrs...
Aww sad you had to give them back but hey 9 more goslings on the way right. Boy that will be fun.
Parents are beautiful. lovely green grass for them to graze, Jealous over here.
Could be a mix then I have an Embden gander and Toulouse female But sadly they have never had goslings. If yours are pure Embden then you have a male lighter one and female dark one. I bet you can't hardly give them up goslings so so precious.
What no pics to verify they are getting more yellow.
Well that's fun kind of like having grand kids you get the joy of having them around for a while and the joy of sending them home too.
If they are Emden they are both females, My Embden gander had some grey on him but not that much and that dark. I say Toulouse my Toulouse gosling looked very much like them. Your not keeping them? surrogate incubator?
You up for some interesting reading? give you something to do while you are waiting. lol
