Find out why she stopped, and what to try first.



Take a photo of any hen. Cooply tells you what is probably wrong, what to do about it, and what to check tomorrow.

Hens hide it when they feel bad. By the time you notice, you are asking around, and every answer you get is a different one.
They cannot all be right, and you cannot drive a hen to the vet every time she looks a bit off.
So you pick one, you wait, and you hope. That is how a small problem turns into a big one.
That’s just a molt. Mine looked like that last year, she’ll be fine.

Worm her. Worming always sorts it out.

Vinegar in the water, that’s what I give mine.

Looks like mites to me. Strip the coop tonight.
11 agreeFour answers, four different problems. Not one of them has seen your hen.
Cooply looks at all five together, because they often share one cause.
Find out why she stopped, and what to try first.
A washed out comb is telling you something. Cooply says what.
Get a plan to grow her feathers back after a molt.
See the likely causes in order, and what to do about each one.
Most give small warnings first. Cooply helps you spot them earlier.
That is the whole app, and every one of them is a hen you keep.
Mites, not a molt
Point your phone at her, and Cooply tells you what it sees.
Cooply remembers her colour from last month, so it sees the change you miss.
Normal
Loose, day 2
Photograph what is on the board, and Cooply names the likely causes in order.

Shut the coop, 18:42
Cooply pings you at the time the sun really sets where you live.
Mite spray $14
Her list holds what the plan needs, so your money goes on the thing that works.
One sick hen, one month, two ways to go about it.
You don’t know how bad it is, so you treat her for everything.
You buy what the forum tells you to buy, not what she needs.
You throw the eggs away, because nobody can tell you if they are safe to eat.
You know how bad it is, and you know when to call a vet.
You see which products help her, and which ones do nothing.
You keep eating the eggs, because the spray Cooply picks is safe.
MichaelPoultry vet, Poultry DVMMost keepers I talk to are searching symptoms at midnight and getting ten different answers. A tool that lays out likely causes, how urgent it is, and what to try first is a much better starting point.
JessicaVet, Vilson Vet. CoI like that it checks the outside causes first, like mites and bullying, before blaming anything inside the bird. That is how I would work through it too.
RobertVet, Four Star Veterinary ServiceMost problems I see get worse because they were noticed late. Daily check-ins and a plan for molt and winter are how I would advise a keeper to run the year.

Wet air hurts her more than cold air does. Cooply puts the vents and the water on your list.
Most chicks that die, die in the first ten days. Cooply walks you through all of them.
Mites live in the coop and feed at night, so Cooply has you check the roost after dark.
