Halachic Hazards relating to raising Chickens:

1. Raising Chickens:[1] [Rishonim/Achronim]

One who raises chickens in his home ends up aging early.

1. Settling a chicken on eggs:[2] [Tzavah of Rav Yehuda Hachassid/Achronim]

One is not to settle a chicken onto eggs in order for it to develop into chicks.

1. Turned over a vessel:[3] [Tzavah of Rav Yehuda Hachassid]

Any chicken or animal which has turned over a vessel is to be immediately slaughtered [within 24 hours[4], or at least within a few days[5]]. [Some Poskim[6] rule that this only applies if the chicken has turned the vessel onto itself.]

1. Placing a chicken near the bed:[7] [Achronim]

Some are accustomed to placing a chicken under the bed of the baby on the night before the Bris in order to protect him from Mazikin.

1. Chicken crowed like a rooster:[8] [Tzavah of Rav Yehuda Hachassid/Shulchan Aruch/Achronim]

If a chicken crowed like a rooster it is to be immediately slaughtered.[9] However, it is forbidden due to the prohibition of Lo Sinacheish, to explicitly say that it should be slaughtered being that it crowed like a crow.[10] If, however, he simply instructs for the chicken to be slaughtered without saying the reason why, then it is permitted to slaughter it upon it crowing like a rooster, and so is the custom.[11] However, some are lenient to even explicitly state why it should be slaughtered.[12]

1. A chicken which laid two eggs:[13] [Tzavah of Rav Yehuda Hachassid]

If a chicken laid two eggs, then it is to be slaughtered right away [at that moment[14], or at least within 24 hours[15]].
