Extreme rabbit moulting?

[firstchoice]

I recently acquired two adult house rabbits.
They stayed as house rabbits over the winter but the summer has been so lovely they went into a (very large) hutch in the spring and are out on the lawn most days for around 6 hours, which they clearly love.

They seem to be moulting a LOT. No bald patches. Eating well. Otherwise healthy and recently vet checked. But just handfuls (seemingly) coming out.

Is it the time of year?

My CurrentBun has just started his moult - he's looking a bit rough around the edges and he's a house bun. It's the time of year. They may need more food as they can get very hungry when they moult. There's no filling my boy when he's moulting.

Ah. interesting to know they might need extra food - thanks.

does it affect their mood?

noth mine have bitten me in the last week - one of them is really 'chompy' atm
