I was given 10 roosters. I took them in planning on having them all processed. I was wandering if it's normal for them to be as small meat wise as they are. They were RIR and barred rock mixes. I know that Cornish X hens are meat birds and that's wgats sold in stores etc. can there really be that big of a difference?? My roosters were crowing and doing everything my old rooster was doing. I got annoyed with all the fighting that was going on and figured noes a good time. But they still seem lanky. Kinda tall and scrawny. Is that normal for non meat hybrid birds?
