5 week old gosling making strange noise

[starrymutt]

One of my 5 week old goslings, after picking it up to put it in the enclosure, made a noise like air was being let out of it. Like hissing but also squeaky or wheezy. It's the only time I heard it and otherwise it seems healthy. Could a 5 week old hiss already? It's older siblings (5 months) have started to hiss and fly (which is a HUGE surprise) and both goslings are living with them now and possibly learning their habits.

Also, do you clip geese wings? I'm both so proud and also really apprehensive that they'll fly away lol

Doesn't sound like anything to worry about. I don't clip wings and when they do fly it's usually just here to there less than 10 seconds airborne. I'm more concerned about them walking off the property.
