I have 9 hens age 4-5 years and one that is 7 years; 4 GLWs, 3 BOs, 1 BA, 1 BR. 8 of the 9 are housed in an open air, roofed coop with a dirt floor, with shavings and straw over that. Fed layer pellets, water, and free range during the day. Number 9 hatched chicks a few weeks ago and is separated from the others; same housing except in a broody pen within the coop on straw and fed the chick starter. I noticed a couple of weeks ago that several of them seemed to have "fat toes" with a little pinkness to the skin where the toes come together. One of the hens had one toe that appeared to have an enlarged joint and the toe was crooked. No lamenesses, discharge, or anything else. Not all of the 8 had fat toes, and the hen with the chicks is unaffected. Didn't know if this was something normal with age and I hadn't really looked at it before. Looked up foot problems here and elsewhere on the web and none of the common foot ailments described seemed like what I was seeing, so I decided to wait and see what developed. The feet seemed about the same to me, until just now. I saw one of the GLWs has much greater swelling in the area of the foot "pad" and is lame on the foot. Haven't been able to catch her yet to examine closely. We had planned tomorrow to sanitize the coop with OxineAH and fill the base of it with sand to improve the drainage. We did have torrential rains a few weeks ago and the floor was wet for several days, but did not seem too bad, plus I added bedding to the floor to try to keep it drier. What are your thoughts? Does "bumblefoot" start out looking like fat toes? Is there something else I should be thinking about?
