That's what I was afraid of! Thank you for your opinion. We only have four so if one is a rooster should I look for a replacement now while they are young or do I just carry on with three?
You could see if the feed store or hatchery you got him from has a policy to give you a refund or replacement. Though most hatcheries will give refunds if you ordered sexed pullets that turned out to be cockerels. It's up to your decision.
If they were sold as pullets they should cheerfully make it right for you. I'd contact them sooner rather than later. It's easier to introduce new birds when they're younger.We bought them from a local farm so maybe I'll wait to another week or so an see he can add him to his flock and maybe trade. Thanks for your help!
