Estimation of the Gender Ratio of Chickens Based on Computer Vision: Dataset and Exploration
The gender ratio of free-range chickens is considered as a major animal welfare problem in commercial broiler farming. Free-range chicken producers need to identify chicken gender to estimate the economic value of their flock. However, it is challenging for farmers to estimate the gender ratio of ch...

Free-range chicken producers need to identify chicken gender to estimate the economic value of their flock.
