Yep I think they are! My male is getting so huge and he can't support his weight for very long before he lays down. Sometimes his legs even start shaking. I give them brewer's yeast every day but it hasn't helped. He acts normal otherwise and runs around in the yard but takes more rests than the female.
How much brewer's yeast are you giving? How old is he? What's the protein percentage in your feed?
Mine doesn't seem like he has trouble standing but his legs do turn in a bit. he also stretches them backwards when he lays down I don't know if that's normal.
my female is super mouthy I don't know if we're going to be able to keep her. she keeps biting hubby and I, she's really good with our daughter though so I guess we will see. its not nibbling exploring its like hiss! bite!
