now before i begin, let me first say that i searched this forum under similar posts (which there are a few) but none of them really seemed to be quite right in this circumstance. Samuel L. Jackson is a 1 yr old Andalusian who came to us with his 5 hens at the middle/end of this summer. everything seemed in order. towards the end of the summer black spots begin to appear on the tips of his comb as well as other areas on it. when he would bang his head (on the sides of their enclosure, getting to excited with the hens) it would bleed immediately. we do not have any other roosters, and our now 4 hens know there place and dare not touch him. this happened before winter and did not seem to get any worse during those cold months and is still present today (has not gotten any worse, nor better.) he is the only one in the flock who has this. the one Andalusian hen, who also has a rather large comb has no problems either. its obviously not affecting him in anyways, he is a healthy weight, gets a lot of free-range time, and is rather spunky and aggressive...but its just ugly! --- what could it be??
