I have four hens total: one Cream Legbar and one Australorp, aged 15 months, and two 5 month-old EEs. The Australorp and EEs have beautiful red combs, but my Cream Legbar has always had somewhat of a lighter comb. At times it looks perfectly fine, but recently it has been looking slightly pale. This is a picture of her this past July, and I thought she was looking slightly pale. And yet... ... this is her in early October, looking perfectly fine (with considerable comb growth, too!). I know that this is the time of year where combs tend to pale slightly, but I suppose I'm worried just because her comb seems to keep going back and forth in its coloring. She hasn't laid in about 2 weeks, but health-wise she seems to be completely fine... except for the comb discoloration, but that may be normal. Here is what she looks like now, somehow with a smaller comb once again: And here's a comparison with my Australorp: What are the possible reasons for such fluctuations in comb size and color? Should we be worried about what the current state of her comb may say about her health? Again, she's eating and behaving completely normally. This is probably my paranoia kicking in, but I'd love a second opinion.
