press space to open the cage, press the up arrow to change background, click on the hen to breed her, click on any chicken to cull them (remove from breeding pen)
in this game you are breeding brown leghorns (said legern) leghorns should have a floppy comb in the hens and straight in the roosters, dont breed to the birds with a red earlobe, duck toe is a defect and a recessive gene so if you breed to it you will have it pretty much forever, squirrel tail is a polygenic trait so by selecting to birds with the best tail angle (around 45 degrees in a leghorn) you can select away from it, what you dont what to do with squirrel tail is breed to a bird with a really low tail as this will result in both squirrel tail and low tail, i drew all the chickens (and the eggs and backgrounds) and i did all the coding, and i came up with the idea, feel free to remix!
