I’m so sorry for your loss, it really hurts losing such sweet birds.We are in the midst of a long thunderstorm that woke us up. My partner went to check on the gosling and it had passed. Looks like it had vomited a few times. I have a feeling it was some kind of infection because of the nasally sound it made sometimes when breathing. We'll have to bury it tomorrow so our little one has closure.
At the very least this was a learning experience. I'm not sure there was anything we could have done differently but we now know more about the different things that can happen to geese and what to look for. We do plan on hatching some next year if the remaining two are a mating pair.
Thanks for your help.
At least the little one is at peace now, carried away to the beyond by the storm. You did all you could, sometimes there aren’t clear answers to what makes a bird sick and we just do the best we can, and you did so much.
