Ooh, yeah this would be a good QoL improvement as I sometimes do this too! Though I'll have to think about / discuss how to balance it. Should the parents also come off cooldown? I don't want to encourage doing this too much, because people might just spam their nests and then cancel them when a better chicken comes along, which takes away from the feeling that they're actual nests...maybe it can be done with an item that goes for 50 eggs or something like that.
