Do chickens really need grit if they free-range?

Free-ranging birds pick some up naturally from soil and stones, but it is not guaranteed to be enough, especially on grass-heavy ground with little bare earth. Offering grit separately removes the guesswork and ensures every bird in the flock has access, not just the more dominant ones.

What's the difference between grit and oyster shell?

Grit is a digestive aid that physically grinds food in the gizzard, since birds have no teeth. Oyster shell is a calcium supplement aimed at supporting egg shell strength in laying hens. They do different jobs and a flock with laying hens often benefits from having both available.

How often should a coop be treated for mites?

A full clean-out with a poultry housing spray during routine coop maintenance is the standard approach, done more frequently in warm weather when parasites breed faster. Catching an infestation early, before birds are visibly affected, is far easier than dealing with an established one.

When should I worry about a hen that seems off?

A bird eating less, standing apart from the rest of the flock, or looking fluffed up and quiet for more than a day is worth taking seriously rather than waiting to see if it resolves. Isolate her from the flock if you can and seek advice on next steps if it does not improve quickly.

Health and hygiene for poultry and pigeons

Keeping hens or pigeons healthy day to day is less about any single product and more about a few basics done consistently: grit for digestion, a clean, treated coop, and noticing changes early. The short answer: grit is not optional for birds without free access to stones and soil, and a coop that never gets a proper hygiene treatment will eventually cause more problems than any supplement fixes.

Grit: not the same as food

Birds have no teeth, so grit sits in the gizzard and physically grinds down food, which means a bird without access to grit cannot digest hard feed properly no matter how good the feed itself is. Free-range birds pick up some naturally from the ground, but a flock in a run with limited bare earth needs it offered separately.

Oyster shell or a calcium-specific grit is a different product with a different job, supporting egg shell strength in laying hens rather than digestion. Both can be needed at once, and confusing one for the other is a common mistake.

Coop hygiene and spotting problems early

A poultry housing spray used during a full coop clean-out helps control mites and general bacterial build-up in bedding and perches, which matters more in warm weather when parasites breed faster. A coop that is only ever swept out, never properly treated, tends to develop a mite problem that becomes obvious once it is already established.

Beyond routine hygiene, the most useful thing an owner can do is notice change early — a hen eating less, standing apart from the flock, or looking fluffed up and quiet is worth investigating rather than waiting to see if it passes, and any of our general UK pet welfare sources are a reasonable starting point for what counts as normal behaviour.
