So, my chicks are almost 2 weeks old. I always take them out of the brooder to let them play, etc. they always end up flying on my legs, feet, shoulders to roost. Well this evening I notice that one chick had noticibly warmer feet than usual. I have a heat lamp on one side of the brooder but there is plenty of room for the chicks to move out of it. Is this chick running a fever? It seems ok otherwise.
