I am well read on integrating chickens and I had a plan for integrating four new chickens into our flock of two. We had ordered four from a local poultry person who was willing to brood them for us until they could go out into the coop. However, my plans have a wrench thrown in them because one of the chicks died at 4 weeks old (not illness). The person brooding the chicks told me that they will order me a replacement in a week or two (about the time that I should be able to bring home the 3 chickens). I did plan on keeping the juveniles apart from my existing two chickens for at least a month because they come from a farm with other poultry. I cannot have 7 chickens in my coop. I am worried about integrating the lone baby chicken with the three older chicks. I figure I have three options: 1) Let her buy the chick and try integrating the baby chick with the juvenile chicks before we integrate the four with the old chickens. 2) Ask if she has a different variety of the same age as my chicks that I could have instead in place of the chick that died (I asked for specific varieties). 3) Only integrate three. Tell her never mind on the fourth chick. Thoughts?
