I have a small flock and an uninsulated coop and the chicken lowest on the pecking order is quite a bit thinner than the other birds. I try to have feed in multiple plces so she has access and I sometimes lock her alone in the coop for a few minutes with a bowl of high protein mix (tuna, yogurt and layer pellets mixed with warm water) to give her extra access to the good stuff. She also isn't welcome to sleep with the other chickens - they stick together but she is always apart from them. Its been 0 at night and all the chickens are fine but I wish I could increase the fat on this chicken and I wonder if getting her some beef suet might be a good thing to try. I donlt want to feed her so much cracked corn that she doesn't eat enough pellets. Would suet be a healthy concentrated energy way to give her a boost right now when its so cold?
