Bloat?

[NHGoater]

Good Morning all. We have three weathered boys. Fred(alpine 2) Coconut (boer/Nubian 8 mo) and Birch (saenen 6 mo) they are all on pasture and hay combo. We hike them on the weekends usually 2 miles. Our youngest Birch looks like an ottoman when he comes in at night. All of them appear to have bigger bellies now than in the summer especially in the evening. They all chew their cud and drink, pee, and urinate well. They don't appear to be in distress. They hike well. When they are on pasture Birch sucks up oak leave like a vacuum. He loves the brown stuff while the other two tend to be more picky.

Is the ottoman appearance bloat or am I being paranoid? maybe it just looks big cause he is still kind of short. He has grown so much since we picked him up.

Thanks for the help
