I'm about to go crazy with these young birds! I have 4 5 month old RIR's. One I was sure was a roo, even posted pics here to check and got that too. NOW another one is growing into feathers just like this other one. The other two are short tailed, and don't have as big of bumps on their legs (like where the spurs would be). That's the only distinction I can made of the 4. Other than today two got in a squabble, and both hunkered down and fluffed up their neck feathers. LOL I've looked for pictures of how to tell but can't find any. Can anyone help??? I've also got 29 2 month chicks and I'm about scared to even start trying to tell the difference in them. LOL
