I would leave well alone i think my jills lost one or two but i havent stuck my nose in because i think that will stress her more.Mine arent that noisy all the time just when theyre fighting to get to the jill to be fed or feeding.But shes doing a good job theyre well fed and although a bit sqeaky at times nothing too serious that i can see.Make sure she has plenty of decent grub mostly moist and leave her too it
