Are you really unsure of the breed of your chickens? You made some pretty strong claims regarding their size as being only 3-5oz for the adults. This is clearly not what you are showing in your pictures of what appears to be averaged sized serama or serama mixes. You clearly have a lot of them. What breed do you think they might be, if not serama? This is very confusing. Are you involved in any of the serama breeding groups? If not, that might be a good place to start to get a handle on what is and is not a serama. PM me if you need any links to breed support groups.
