What is the difference between the zakah of livestock and the zakah of birds?

Question : This questioner is asking about a question regarding motivation. He says: Honorable Shaykh, what is the difference between the zakah of livestock and the zakah of birds?

Answer : Yes, yes. The answer to the question is that we say: What is the difference between the prayer of the traveler and the prayer of the resident? Or the prayer of Dhuhr. The prayer of Fajr, or between the prayer of Fajr and the prayer of Maghrib. Or am I busy.
It is established in the Sunnah that zakah is obligatory on livestock. There is no zakah on birds and their like, because they are like what the Prophet (peace and blessings be upon him) said: If they are prepared for trade, then there is zakah on them. Accordingly, there is no animal on which zakah is due except livestock. However, there are conditions that must be met: they must be grazing, meaning they are left to graze and their owner does not know their whereabouts. As for those that are fed, if they are not kept in a stable except for a short time and they graze most of the time, the ruling is that of the grazing animal. If the opposite is the case, meaning they are fed for most of the year, then there is no zakah on them unless they are for trade.
