5 days ago I had 11 birds. Today I have 18. My daughter went to a friends house. When my wife and son went to pick her up they came home with 3 chicks to light or white RI and a delaware. Tonight they went to watch her play basketball (same friendo on same team) and they came home with 4 more chicks, all RIR. Now here's the question. How old do they need to be before I can add them to the birds I have (which were born a week before good friday(5 months)). Also what about quarintines for the new birds? Evidentally the man raises hundreds of birds a year to sell of several types (chickens, quail, phesant, peacocks, and geese to name a few). How much area will I need for a coop for all the birds? Will one bird roosto over another bird or do they all need to be at the same level? HEEEELLLLPP!
