Do my hens appear the right size for 7 weeks old? Am concerned because I was feeding them scratch for about 3 weeks after they turned about 2 weeks old at the WRONG instructions of the feed store where I bought them!! They've been back on starter feed for about 2 weeks now. However I'm concerned about their size cause to me they seem huge!! I was told if they're too big/fat they won't lay eggs!!?? Can anyone tell me if they appear size consistent with 7 weeks of age??
