NutritionFacts.org has a very informational video regarding eggs and how unhealthy they are, regardless of how much pressure the egg industry puts on researchers and the government to say otherwise:
FreeFromHarm.org also has a great article on exactly what eggs are and helps dispel the myth that eggs can be produced harmlessly:
Chickens were only ever domesticated for one reason: to exploit them. All chickens used for meat and eggs are the result of centuries of violent domination and decades of invasive genetic manipulation that dooms even those lucky enough to be rescued to a lifetime of unnatural frailty and disease. This means that all eggs, even those from rescued hens, are the product of injustice. Since humans have no biological need to consume eggs, we can withdraw our support from this exploitative industry by choosing plant-based egg alternatives for baking and cooking.
