If the peanuts are sticking together or looking a bit mouldy, throw them away and clean and rinse the feeders thoroughly. It's fine to offer them in feeders as they can't get whole ones out that will then choke their babies. Don't offer them as loose feed.
I keep all my peanut, fat ball, insect block and loose seed feeders topped up all year so that I have healthy adults prodcing healthy eggs and with the energy to forage for insects and larvae to feed their young who need juicy food for its moisture as much as its protein to grow well. It works very well and I never have to spray for pests.
However at certain periods of the year they forage in my garden, local fields and woods so consumption of my offerings slows down. Even the best quality peanuts can get a bit mouldy if left long enough, particularly in wet conditions so it's just a case of regular checking and cleaning as necessary.
