My NN roo has seemed a bit out of sorts for the last day or two....nothing I could put my finger on. Today I noticed him standing on one leg and limping badly when he tried to weight bear. On inspecting his foot, the 'pad is very swollen and hot (no definite scab) and the whole foot and 'ankle ' region is swollen too. He felt very light in weight. I have never had a chicken with bumblefoot, but looking on the web it looked rather similar, though no scab. The 'pad' felt fluctuant, so I inserted a wide gauge needle to see if there was any pus, but only blood came back. the foot looks very infected, so I gave him a very small dose of our veterinary penicillin (Unicillin La....Procaine penicillin G 150,000units and Benthzathine penicillin G 150,000units per ml.)...being a weekend and miles from vet. help until tomorrow. i gave the injection to the side of the breast bone as suggested in one article (though others suggest the thigh).I have crushed aspirin into his water and bought him indoors. His appetite seems excellent. Could anyone please advise as to what further I can do?....I remember somewhere reading about iodine and sugar poultices. What is the best dose of penicillin to give...or shall I get a different antibiotic from my vet tomorrow? Where is the best place to inject? Any other suggestions as to what I need to do? Thank You.
