Artificial Insemination of Poultry
Catherine Stasevich produced this video explaining how to artificially inseminate chickens. Catherine recommends trimming the feathers around the vent on the male for increased visibility and also so that they don't soak up the semen. The pipette used to collect the semen is a 1.3ml micro pipette.

Written instructions on AI can be found in the poultry breeding section, although you may want to refer to this video again afterwards as it is easier to see someone doing it rather than reading about it.
