It is Sunnah to make the animal face the qiblah at the time of slaughter
Question

                If a man wants to slaughter a chicken, does he have to make it face toward the qiblah or may he slaughter it no matter what direction it is facing?.
Praise be to Allah.The Sunnah with regard to 
    slaughter is to make the animal face towards the qiblah, but that is not 
    obligatory. If he slaughters it facing any other direction, his slaughter is 
    halaal, but he has omitted a Sunnah. 
Ahmad (15022), Abu Dawood 
    (2785) and Ibn Maajah (3121) narrated that Jaabir ibn ‘Abd-Allaah (may Allah 
    be pleased with him) said: The Messenger of Allaah (blessings and peace of 
    Allah be upon him) sacrificed two rams on the day of Eid. When he turned 
    them to face towards the qiblah he said: “Verily, I have turned my face 
    towards Him Who has created the heavens and the earth Haneefa (Islamic 
    Monotheism, i.e. worshipping none but Allaah Alone), and I am not of 
    Al-Mushrikoon .Verily, my Salaah (prayer), my sacrifice, my living, and my 
    dying are for Allaah, the Lord of the ‘Aalameen (mankind, jinn and all that 
    exists). He has no partner. And of this I have been commanded, and I am the 
    first of the Muslims’ [cf. al-An’aam 6:79, 162-163]. O Allaah, from You and 
    to You, on behalf of Muhammad and his ummah. In the name of Allah and Allah 
    is most great.” Then he slaughtered them. 
The isnaad of this hadeeth 
    may reach the level of hasan as Shu’ayb al-Arna’oot said in Tahqeeq al-Musnad. 
It says in al-Mawsoo’ah 
    al-Fiqhiyyah (21/196), explaining the etiquette of slaughtering:
The slaughterer should face 
    towards the qiblah and the animal’s neck should be turned to face the 
    qiblah, because Ibn ‘Umar (may Allah be pleased with him) disliked eating 
    the meat of any animal that had been slaughtered facing any direction other 
    than the qiblah, and no one among the Sahaabah disagreed with him. That is 
    narrated in some reports from Ibn Sireen and Jaabir ibn Zayd. End quote. 
See: al-Mughni, 
    3/221 
It says in Fataawa 
    al-Lajnah al-Daa’imah (22/477) concerning one who slaughters an animal 
    facing a direction other than the qiblah and claims that making it face the 
    qiblah applies only when slaughtering the hadiy: 
If the situation with 
    regard to slaughter is as you say, then the slaughter is sound and valid in 
    terms of it being halaal, but the slaughterer is going against the Sunnah by 
    not turning to face the qiblah with the animal at the time of slaughter, and 
    he is doing wrong by not accepting the advice, and he is mistaken in his 
    claim that making it face the qiblah applies only when slaughtering the 
    hadiy, because the Sunnah is to turn towards the qiblah with the animal at 
    the time of slaughter in all cases, whether it is a hadiy or a sacrifice or 
    otherwise. End quote. 
It also says (1/67): It is 
    mustahabb for the slaughterer to face towards the qiblah  and to make the 
    animal also face towards the qiblah, because it is the noblest of 
    directions, and because turning to face the qiblah is mustahabb in acts of 
    worship, except in cases where there is evidence to indicate otherwise. The 
    fact that this is mustahabb is particularly emphasized if it is a hadiy or 
    udhiyah. It is narrated from ‘Aa’ishah (may Allaah be pleased with her) that 
    the Prophet (blessings and peace of Allaah be upon him) said: “Offer your 
    sacrifices and be of good cheer, for there is no Muslim who turns his 
    sacrifice to face the qiblah but its blood and dung and wool will be 
    hasanaat that are present on his scales on the Day of Resurrection.” And he 
    used to say: “Spend a little, you will be rewarded a great deal.” This 
    hadeeth was narrated by ‘Abd al-Razzaaq in al-Musannaf, and 
    al-Tirmidhi, Ibn Maajah and al-Bayhaqi narrated something similar. Although 
    the imams of hadeeth suggested that its isnaad is weak, it may be acted upon 
    with regard to encouraging good deeds. Hence Ibn ‘Umar and Ibn Sireen 
    regarded it as makrooh to eat meat that was not facing the qiblah at the 
    time of slaughter. Limiting oneself to saying Bismillaah and letting the 
    animal face any direction at the time of slaughter is forsaking that which 
    is better, but the slaughter is still valid. This was the view of al-Qaasim 
    ibn Muhammad, al-Nakha’i, al-Thawri, Ibn al-Mundhir and others. End quote. 
And Allaah knows best.
