So, I have 3 eggs set to hatch out this coming Saturday. My question is, how old do the chicks need to be before I can put them with my established flock of four consisting of 3 hens and a rooster that are all PBR. Of course I wont put them out the day they hatch but i dont want them in my house until they are equal in size either! I've researched and I have found so many different answers from 7 weeks to 16 weeks. I've heard put them out at night when everyone else is asleep. But not sure how effective that is. I've heard to make a area in which they can see one another but not get to eachother. Any help would be great!! i do plan to keep the chicks in a rabbit cage in the house until about 6 weeks! Thank you!
