Aesa kon sa janwar h Jo and a dudha dono deta h?

Aisa janwar jo anday aur doodh dono deta hai, wo hai "murgi" (hen). Murgi anday deti hai, jabki kuch prakar ke mammals, jaise ki "dahi" (platypus) aur "echidna," bhi anday dete hain lekin doodh nahi. Lekin, aam taur par, doodh dene wale janwaron mein anday dena nahi hota. Isliye, yeh sawal thoda tricky hai, kyunki murgi hi ek aisa janwar hai jo anday deti hai, lekin doodh nahi.
