We got 10 EE's exactly 5 weeks ago. Is there any rhyme or reason as to why 1/2 of them are two times the size as the others? One of them is as small as my almost 3 week old BRs and BOs! We did get them from the feed store and they said they were all EEs/Aracauna/Americanas. ....He said they're all the same.... (I know now that's not the case, but I don't care really what they are!) I'm a real newbie. Any thoughts? Thanks so much!
