Greetings - LOOOOONG story short - I have ended up with a flock made up of one 5 month old black silkie hen. I would like to have two more chickens - for a total of 3 birds. I have been reading that I am better off to stick with silkies - which is fine - but what age silkies should I get. My hatchery has them in all age ranges..... Thank You!!!!
