It seems to be going much better. He now stands on his own and the wings are no longer hanging. I'll check again later and give some food and water.
I just gave him extra water, he wasn't really thirsty. I left the water in the coop so he can drink if he wants. Later tonight I'm going to bring some food and see how it goes.
Is botulism also something that arises so acutely? I went to have a look at them today around four o'clock and then there was nothing visible and two hours later he could no longer stand on his legs. Now a few hours later he can stand and walk independently again and is a lot more alert. But I can still see from his appearance that it is not quite right yet...
Indeed, he can choose whether he lies against the hot water bottle or not.
I'd rather not bring him in because I'm afraid that will cause him extra stress. I have two ducks, so the other one would have to come in too or be left alone. I'm just afraid that it disrupts them too much.
The temperature is currently around freezing, so not really extreme, it is warmer during the day.
