It would be great to have an item that would allow you to choose your cow, sheep, goat and pig to be pregnant rather than waiting for the random chance of them giving birth. The price of it could be half of the price of the original animal like for example: The Pig is bought at marnie's ranch for 16,0000 gold and the Said "Pregnancy pot" for pigs would cost about 8,000 gold. And the amount of time until it gives birth would be like 2 - 3 weeks in game time. Having another option like this other than waiting for chance would be really great specially for farms that has a focus on animal breeding it would lessen the cost and time needed to have a full barn of animals
I always wondered who is impregnating my cow in the middle of the night, because I didn’t have a bull and I never paid for a service to breed my livestock. Pregnancy pots would be a workaround.
