My husband would like to add peafowl to our menagerie. We live in Ky and already have chickens that free range during the day and a human toddler as well. Are there any varieties that are more hardy in cold or more friendly. What age would be best to start with? I have hatched chicks,ducks, and geese...are they hard to hatch? How early can they be sexed? Thank you in advance for any info!
