Hi BYC community, Your thoughts please. One of our chickens has a swelling under her eye. It's been there for a while. It seems to be getting a little bigger. She seems happy, healthy and is laying. But we're wondering about the swelling and what to do about it. Would it, for example, be sensible to try and lance it? (is it likely to be full of liquid / puss?). Full questions answered below and photos attached. Thanks in advance, Best, Miles 1) What type of bird, age and weight (does the chicken seem or feel lighter or thinner than the others.) Type: Wyandotte. Age: 18 months Weight: Normal. Comparison to others: About the same. 2) What is the behavior, exactly. No change in behaviour. Just a swelling under the eye (see photos). Eating and drinking. Normal. Apperance. Normal. Crop seems OK. Vent seems OK. 3) How long has the bird been exhibiting symptoms? The swelling has been there for a number of months, but very slowly it seems to be getting bigger. 4) Are other birds exhibiting the same symptoms? No. 5) Is there any bleeding, injury, broken bones or other sign of trauma. Nothing apart from the swelling (see photos) 6) What happened, if anything that you know of, that may have caused the situation. Nothing. 7) What has the bird been eating and drinking, if at all. Normal food (layers pellets in run, grass when out) and drink (multiple fresh water sources) has been available. 8) How does the poop look? Normal? Bloody? Runny? etc. Normal. 9) What has been the treatment you have administered so far? None. 10 ) What is your intent as far as treatment? For example, do you want to treat completely yourself, or do you need help in stabilizing the bird til you can get to a vet? Doesn't seem to be an emergency, but something we'd like to get ontop of. Either ourselves, or using vet. 11) If you have a picture of the wound or condition, please post it. It may help. See photos. 12) Describe the housing/bedding in use Housing: Normal. No change. Bedding: No change. Woodshavings.
