I purchased to Cochin hens not too long ago and they are very active birds. They eat well every day, take their dust baths, look bright in the eyes, and act like healthy chickens in general. My concern is their keel was sharp to begin with and they do not seem to have gained any weight even though they have access to 16% protein pullet feed all day everyday plus treats. I don't think I should be worried about impacted crops since they are very active and have a great appetite, and no funny smell. The odd thing I did notice is when they cooped up for the night last night they had super full crops and this morning they still have a slight palpable crop however my BR does not have a palpable one even she too went to bed with a full one. Yes the birds have access to food and water through the night. Could it be that when I am home on my weekends they are just allowed to roam freely in the back yard all day? it is total of 5 days of free roam a week because of how my DH & my weekends are arranged. Should I confine them for a week to make them gain weight? Or should I even be worried at all? I have had the birds for almost 2 weeks now.
