Chickens will only eat grain placed in small troughs. Hens need to reach a satiety of 6 before they are ready to mate. For now, baby chicks are not preceded by eggs - they appear like other baby animals. The pregnancy takes 9 days for the hen and there will be 1-2 chicks, with a "cooldown" of 6-9 days before the next pregnancy. The chicks will grow up after 168 hours, with a 90% chance for more hens and only a 10% chance for a new rooster.
Hens will lay eggs on the ground every 8-15 in-game days, which can be used in cooked foods but do not have any impact on breeding new chickens. Players should collect the eggs regularly, as they disappear within 2 days.
