Chicks now 4 weeks old.

They are so much bigger now! They move so much faster - you cannot catch them now! Just waiting to see whether they are going to be hens or cockerels!! I hope that I am wrong but, I have a feeling that 3 of them are cockerels!! Ideally, we would like four hens then we would keep two and my friend would like two. Oh well, let's hope I am wrong.
