I apologize if I am posting this in the wrong place. I just joined and I am a first time chicken owner. We started with 2 day old bantam chicks which are now 5 weeks old. We have 2 silkies, (a buff and a blue), a Brahma, and a Rosecomb. We are keeping them as backyard pets and my children will be doing 4H with them as well. We live in a residential neighborhood and are only allowed to keep hens. Luckily the farm store we bought them from will happily take any roosters back from us. We've already had to bring one back after it developed quite a prominent comb around 3 weeks of age. They were surprised that he was showing so early but said he was definitely a rooster. They swapped him out for us with another chick but warned me we could have problems with the other chicks picking on it. Luckily they were all young enough that the new one fit right in with no problems. Our buff silkie has a light colored beak and has always had a larger bone structure than the blue and this past week it's comb has gotten raised, lumpy, and is turning a bright pink. It's head is also narrower and it is much taller than the blue so we're pretty sure it's a rooster and will have to be returned to the store. The blue silkie has a black beak and comb so I don't see it turning pink or anything. I can see a difference in width and shape (it is narrower than the buff) of the comb though and it has a rounder head so I am hopeful it is a hen. We're pretty sure the Brahma is a hen but I have no idea how soon we'll be able to tell if the Rosecomb is a rooster. The Rosecomb is just starting to develop a comb and I have no idea what it would look like at this stage for a hen or a rooster anyway. We wanted to have 3-4 chickens but now I'm worried we're only going to end up with two. From what I have read you shouldn't try to bring more chickens into an established flock because they won't accept them. Any ideas what I should do? We're really attached to these guys and bringing them back to the store is so hard. I know chickens are really social animals and we don't want them to be unhappy or lonely. With so few in our flock does anyone recommend we try bringing in a couple more or is it too late for these guys and it is what it is? Thanks if you made it through this long post and I appreciate any advice for this newbie.
