text: Yo, check it out, I'm 'bout to drop some knowledge,
  Talkin' 'bout the eggshell and its proteinaceous college.
  The outermost layer, known as the cuticle,
  Regulates water exchange, keeps it cool.
  
  Micro-organisms tryna invade,
  But the cuticle's there, it's got 'em dismayed.
  We did a study, put it to the test,
  Hypothesized it might defend against the pest.
  
  We extracted proteins from chicken, duck, and goose,
  Treated 'em with HCl, urea, no excuse.
  Checked the extracts for their antimicrobial might,
  Against Gram-positive and Gram-negative, day and night.
  
  C-type lysozyme, ovotransferrin too,
  Ovocalyxin-32, they all came through.
  Western blotting showed they were in every extract,
  Lysozyme activity, that's a fact.
  
  Even when immobilized, lysozyme still had game,
  Kept on fightin', ain't that a shame?
  Protein extracts showed they could kill,
  Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis, they fell.
  
  These findings suggest a powerful notion,
  Avian species got a secret potion.
  Antimicrobial proteins in the shell,
  Helpin' birds succeed, you can surely tell.
  
  So next time you crack an egg, you know the deal,
  Appreciate the cuticle and its rhyming skill.
  It's a mechanism for avian success,
  Keepin' them safe, no need to stress.
