I have a pair of hens raising 3 poults together. The poults are almost3 weeks old, but we would also like to add 4 more poults to be for dinner later. Is it still possible to add poults so late or not? I know with chickens the window of opportunity is not very long. The hens are very sweet with their babies and tolerant of people. Since there are 2 mamas working as a team, I was wondering if maybe they might take more if given an opportunity.
