I'm starting to see similarities between one of my red sex links and a RIR I had before. I once had this RIR who I probably should have let die when she was a little chick because she was so weak but my husband and I kept at her and made her healthy. She got sick a lot, if she got worked up or scared she had breathing issues and could even pass out from them. It took her a full year to mature before she started laying. Now I have a red sex link (possibly related, not sure because I don't know if their daddy was the original RIR's brother or not) and this little girl is a bit healthier and definitely has more spunk but we helped her hatch (my husband couldn't stand letting her die after she pipped). She was born February 19th and has pretty much no wattles or comb and her face is just starting to turn a light pink colour... whereas the others have laid and have bright red wattles and the chickens themselves are enormous (she is tiny). Anyway today she had breathing issues when she was being held by me because she was nervous. I sat her down and my dog came to smell and she flopped over like she was drunk (very much like my old RIR) would have done. It seems so odd that they both had these same issues. It makes me wonder if she will mature and lay wonky looking eggs like the other one. Has anyone else had this experience?
