Hi Everyone! I am new to this forum and would like to introduce myself. I am mtnfam and have 30 chickens that I ordered from McMurrey hatchery. They are all beautiful and healthy except I am concerned about a growth on one of the hens head. It is above her eye and keeps getting bigger. It looks like it is filled with fluid and kind of has a head on it. But I don't know if I should pop it to drain it or let it do it's on its own. I keep thinking let it do it on its own, but it is going on a month now and it just keeps swelling. It is not hot to the touch. She is perfectly happy and eats and drinks and the others don't seem to notice it. Should I leave well enough alone? Any ideas what it is. Here is a pic. To me, it looks like a blister of sort. My chickens are 14 weeks old. I would appreciate any comments on this. Thanks!
