Is it permissible to place a freshly slaughtered chicken in a 5-liter container to collect the blood and prevent it from splattering?

Excellence must be observed in all things, including slaughter, by bringing comfort to the animal. Jurists have agreed upon the desirability of perfecting the slaughter of an animal to ensure its comfort as much as possible. Among the forms of this excellence is allowing the animal to move after slaughter, and for the slaughterer to place his foot on the animal's neck and hold its head with the other hand to slaughter it with force and speed, while severing the jugular veins. Its legs should be left unrestrained to allow it to move and drain more blood, and its legs should not be tied or sat upon, as leaving them unrestrained is better. A small container prevents the animal from moving, so it is better to use a larger container like a barrel.
