Thanks for the replies guys.
We have only had him for three weeks but he has always been this way, I think his character is brilliant and I like that he is 'special' he just potters around the garden eating everything then stands around doing nothing until you throw some peas and he's on them like a rocket, often barging the girls out the way! It's only the couple of falls that got me worried.
His relationships duck to duck are fine but that's all. No fighting but he will happily wonder off completely seperate from the others which none of the girls would dream of doing.
Cider vinegar in his drinking water? Will that be ok for all the flock?
Ducky vitamins - any recommendations? I will order them online.
As far as the shape goes, yes, his chest almost seems too far forward, malformed or pet quality maybe but that's fine with me, he's great! I just don't want him suffering. I don't handle him but could catch him for a bath. How warm is warm?! (Daft question!) .......... Now that I think of it, he preens but doesn't ever swim in the pool. He also looks a little scruffy, has since I got him. It's like he isn't quite waterproof but he loves the rain and even more, the mud!
I am indeed in the uk, sorry I didn't think about that!
Thanks again.
