hi all, ive been a long time lurker first time poster and sadly my first post is in this section. i have around 15 hens and 2 roo's, all mixes and 10 muscovie ducks. i also have a few adorable little chicks. ive recently been losing a few chickens to unknown causes. they seem fine one day and dead the next. the only thing ive noticed not right with the poultry is the red bit round the face on one side looks swollen and the bird gets a sort of frothy foamy glob in the corner of the eye on that side of the face. none of the dead chickens have shown this symptom before dying, so dont know if its connected or not., ive checked everyone over thoroughly, listening to chests searching for bugs. every one seems 'healthy' no laboured breathing or crackling sounds, no discharge in the mouth/nose. all poops look normal, but egg production has dropped from 15 per day to 7 per day. one muscovy is also showing the foamy bubble in the eye thing, but ive read this can be a sign of stress in ducks so dont know if thats the same as what the chickens have. ive so far lost 4 hens and one roo since january. they used to free range but after seeing a fox in the area i built them a large coop (50metres by 50metres) so they have to stay where i can see them now. this was built in january. everyone is wormed twice a year and the houses are cleaned out, disinfected and dusted for mites every season i put everyone on a course of denagard for 10 days but i dont think it did anything. im not sure where to go from here. my hubby wont let me go to the vets with a chicken, he says for the price id pay to get 1 seen, i could buy a whole new flock. he's right in a way but i care that little bit more about my chickens than he does and couldnt just 'replace' them like that. so if anyone could share their wonderful knowledge with me about what this could be, id be so grateful we live in northwest uk, so weather is forever changing here, i guess that doesnt help.
