Hello everyone.
I have a big problem. I have a muscovy on a huge clutch of eggs but today I noticed she has a huge abscess on the side of her head..

it is big, pink and shiny and looks so painful. I do not know what I should do about it. Do I risk her leaving the clutch by bringing her inside to lance the boil or do I allow it to naturally break on its own and leave her in her nest??
I also noticed the way she plucked her own down to make her nest. It is very fascinating to see a muscovy make a nest just like rabbits do.
