I hope someone can help me with a problem we're having with 2 African Geese: Our geese are about 13 weeks old, and two of them, Fred and George have started collapsing from what seems to be exhaustion. They run around and try to fly and then just collapse. Last night it was Fred. Now Fred is the one who had some sort of catastrophe when he/she was about 6 weeks old. We found him feet up near the garage and he could not stand up without falling over. After a night in the house with me feeding watermelon to him (it seemed as though it was the best way to get electrolytes to him without causing more stress) he eventually recovered about 70%.
Georgie collapsed this morning. As with Fred, I scooped him up and took him to the pen so he can be isolated and rest until he caught his breath. Georgie wasn't having anything of laying on the straw, so he got to hang out on my lap. After about 5 minutes, he recovered enough to put up his head and tuck in his wing. I noticed he was shaking a bit though. The rest of the flock came over and must have talked him into coming with them, because he squirmed and I put him down.
So questions: Has anyone had an experience like this? What more could we do for Fred and George? As our aim for the flock was to get 2 breeding pairs and put the rest in the freezer, we're sure Fred and George will be getting the short straw, but should we even wait another month? Any advice would be great.
I dont know if this would help, but it cant hurt! How about adding some vitamins/ electrolytes to their water? Maybe it will help make them stronger and perhaps give them any nutrients they're low on? Ive heard of Nutri-drench (make sure you get the one for poultry, because they have products for other livestock) but I've used sav-a-chick in the past, just sprinkled in their water as a supplement. Here's what they look like:
