My son's favorite chicken (isn't that always the way?) has developed swelling around her bottom jaw... she is eating well, behaving normally he just noticed it when he picked her up today. He's been down with the flu all week so we aren't sure how long this has been going on since he's the one that usually tends to them and spends most of the time with them. My husband has been watering, feeding and cleaning for them this week but rarely picks them up for a chat like my son does. We got a quick peek inside her mouth and there doesn't seem to be anything that looks like an ulcer or other type of sore... no pus etc. Just swelling around her lower jaw. I did take pictures and hopefully I can figure out how to post them. Ok there I got the pictures to post... bear in mind she was foraging before he picked her up so the black you see around her mouth is dirt... she does have some black specks on her comb which she and our other leghorns have had on and off since we have had them (the past six months) I want to do the best for her but have to do whatever needs to be done as economically as possible as my husband is currently unemployed. Any ideas as the what this is or what should be done? Thanks so much!!
