Some farmers will take a roo in exchange for a pullet if they have a separate pen for roos/meat birds and if you shell out a few bucks along with it I'm sure they would be more than happy to oblige. . You could also see if your local feed store will take him for free and re home him. There is also your local Humane Society you could bring him to but I'm not sure if that is free or not. Seriously, I know that whoever recommended you get another chick to keep your remaining pullet company meant well, but you can't put a younger smaller bird with one that is as old as the pullet you are going to introduce to your flock. Like many in the thread suggested, you need to get another pullet the same age as the one you have now but you will probably have to keep them separate in an area they can see each other but not interact until you know they will get along. Chickens who don't know each other don't automatically become friends. The scenario is usually that they fight, sometimes until one is horribly injured or dead. It took me 2 and a half months to integrate 2 easter egger pullets into my flock. Lesson learned the hard way because I put them together with my older flock when my easter eggers were about 4 months old and the one was almost picked to death (they got along for 3 days, the fourth day the flock attacked one of my EE pullets). I switched to segregating them from the main flock in an adjacent pen for 2 months until the older hens accepted them. You will probably have to do the same thing. What I suggest is you keep your roo with your pullet as long as you can if you can't get another pullet the same age as your existing pullet. Start looking for the right aged pullet to replace your roo now. Keep your roo until you find a replacement for him. Some roos start crowing earlier some much later. I had a roo that didn't crow until he was 5-6 months old so don't anticipate his crowing will be an issue right away. Have them together in a separate enclosure in your chicken run starting now if you can, where your older hens can see your pullet and roo (or pullet and pullet if you find one) but can't interact with them to hurt them. In a few weeks or a month or two you may be able to release them into the main run. When all your chickens are getting along, at that point you could get rid of your roo if you haven't found a replacement for him.. Thats my suggestion anyways. Hope this helped. Of course, this is assuming your roo is a roo. A very close up picture of the comb would really help us identify sex. Pullets that have a pea comb like yours does will have 1 row of vertical "peas" in their comb and a pea combed roo will have 3 distinct rows.
