Is it possible for a duck to get too heavy for its legs? My muscovy drake has gotten very much on the plump side as of late, and spends alot of time sitting. He can walk, he's just slower and waddlier then the hens, and there appears to be no sign of injury, soreness, lameness, illness, abrasions etc. He doesn't seem to ever stop eating.
. They do free range alot which use to make up most of their diet but since adding chickens to the mix they have become greedy guts. Okay think its time to persue making my own mix I'd love him to live that long!
