Dua when rooster crows

Q: I live in the countryside and in my courtyard I have six hens and a beautiful red rooster, masha'Allah. The rooster crows many times a day. It starts before sunrise and it stops after sunset. It crows especially when I listen/recite the Quraan or Durood Sharif, masha'Allah. I'm really happy of this thing because I know that Imam at-Tirmidhi reported in his Jami' that Abu Huraira (radhiyallahu anhu) narrated: "The Messenger of Allah (sallallahu alayhi wasallam) said "When you hear the crowing of the roosters, then ask Allah of His grace/bounty, for verily they have seen an angel, etc.". So when I hear the crow, I recite various duas sometimes in Arabic and sometimes in Italian, but I don't know the specific du´a for this case. Well, I'd like to know the best du´a to say when I hear the crow of my rooster (in transliterated Arabic, please).

Making dua to be blessed with male children

Q: I am the eldest child of my family (a male), and have 4 younger sisters Alhamdulilah. I am also Alhamdulilah married and have 2 children (1 boy and 1 girl). However, when I was younger I always wanted to have brothers but never did.

Is it permissible to pray to Allah Ta'ala for Him to bless me with more son’s or only sons if I have future children inshaAllah? Before my daughter was born, I made a lot of dua to Allah Ta'ala to bless me with another son but I was still very happy Alhamdulilah to be blessed with a daughter. But I would really want my other children to be sons InshaAllah. Please advise what I should do?
