We have the same thing going on with 2 of our Ameraucanas. They seem healthy, just not growing as fast as the others. I know Ameraucanas can range pretty widely in size tho. Unsure about red sexlinks. I'll definitely be watching to see the experienced chicken people weigh in on this tho.
And welcome to the Forum!
Curious to see if anyone else has a Facebook page devoted to their chickens/farm. Anybody? You show me yours and I'll show you mine! LOL
I do, I do!
