We are rebuilding our flock, and are adding about 6 more chicks to our 3 remaining girls. (We have an Easter Egger who is about 6.5 years old, a Golden Cuckoo Maran who is about 5 years old, and a Bantam Brahman who is about 4.5 years old.) We just got 4 chicks over the past week: 2 Columbian Wyandottes, 1 Barred Rock and a Buff Polish. My question is this: we want to get 2 more chicks, should one of our 2 chicks be another Polish to keep the first one company? Thanks for any info/advice!
