Camel in Steal an Egg

Camel (Rare rarity) belongs to the Desert zone. Desert is zone 3 of 12 on the wiki's Biomes list; the wiki lists its entry requirement as 10K speed, and the nests there are watched by the Scorpion. You get it by carrying the Camel Egg back to your pen.

At $75/s base income, Camel sits 6th out of 8 in its zone — Royal Sphinx tops the Desert at $280K/s. The listed figure assumes no mutation and a normal weight.

With a colour mutation and no size bonus, the same Camel would earn roughly: Silver ×1.2 ≈ $90/s, Golden ×2.5 ≈ $187/s, Rainbow ×3.5 ≈ $262/s (multipliers from the wiki's Mutations page; arithmetic is ours). Add a Giant (×3) or Huge (×5) size roll on top and the numbers multiply again.

Hatching it pays a one-off reward of +9k Speed, $7.5k, and the egg takes 45s to grow in the pen. That reward is the reason low-income eggs are still worth stealing early: the speed bonus is what gets you into the next zone.

A Rare is usually the first egg in a zone that is worth waiting out the 5-minute nest reset for.
