The Ultimate Chicken Care Guide: Caring for Them, Disabled Chickens, Enrichment and More

Feels rather unfocused which leads to insufficient detail despite the (impressive) article length. However, your formatting is splendid, easy to read, and even has photo credits!
Casportpony already mentioned a few concerns about the accuracy of some of the information so I won’t repeat them. Overall nice work and with some tweaks - maybe even turning it into a multi-page article if you want to keep the scope - it could be even better.

Good start.

In common chicken diseases, you list bumblefoot, Newcastle, avian influenza, fowlpox, and coccidiosis. Of the five, coccidiosis is the most common.

How about Marek's, parasitism, egg binding, and mycoplasma?

The Chick Care section needs some edits.

• A brooder is needed, but does not have to be large, and it does not have to be round.
• Three to four inches of bedding is too deep for newly hatched chicks.
• You wrote: "Feed chicks a special crumble diet for the first few weeks of their life." & "Chicks should be transitioned to layer feed at 18 weeks old". That's confusing. Is it a few weeks or is it 18 weeks?
• "special crumble diet" should be "chick starter"

The Breeding and egg incubation section implies that chickens only breed three months of the year and does not explain that a hen lays an egg every 1-3 days, that they lay several eggs before going broody, or that some hens never go broody.

The How to care for disabled chickens section says "Most disabled chickens are permanently non-ambulatory". There are several non-ambulatory disabilities. For example: cross beak, one wing, one leg, & visually impaired.

Informative article.

The article is well written, however it is "standard wisdom" some of which I disagree with. Examples would be space requirements. These are not absolute. Large breeds, such as brahmas, need more than 8 sq ft run space. Housing/indoor space will depend on the size of the chickens and your climate. In my hot, humid climate, I need more run space in relation to coop space.
Brooder temperatures are also subjective. I do not believe in the standard formula.
I use broodies to raise chicks for the most part. Momma hens will take their chicks out in every kind of weather. As long as they can get under mom to warm up, and find comfort as needed they will be fine.
I think the op needs a little more hands on experience, but as a whole the article is informative.

Thank you for taking the time to write this article. It is thorough but succinct to keep the readers attention.
