I now have a horrible feeling it could be lead poisoning! I found this on fowlfacts (
http://fowlfacts.proboards.com/index.cgi?board=afflictiondiseaseff&action=display&thread=1654)
"7.2 mg/kg is lethal
Symptoms:
Blindness
Moping
Drowsiness
Weakness
Depression
Ruffling of feathers
Abnormal wing carriage
Thirst
Emaciation
Loss of appetite, total lack of desire to even try to eat
Diarrhoea
Bright green droppings
Convulsions
Loss of mobility
Paralysis
Sudden death
Reluctance to fly
Treatment:
Flush out the crop
Give Electrolytes and Glucose
Isolate
Keep the area clean
Give fresh water and feed
Keep warm and out of the elements
If blind…. Remove any obstacles. … put feeders and Waterers up off the ground or make them large enough the bird will find them easily
Don’t move things around, as it will confuse the bird"
We haven't got any lead paint anywhere near the coop
but we have just had our sash windows refurbished and the chap (read
useless idiot) who did the work added extra lead to the weights. This involved shaving bits of lead off a block until it weighed the right amount and he did it right on the paving in front of the run while we were out. Of course he didn't bother containing the lead shavings or even tidying up - I had to do that myself and although I thought I got it all it's not beyond the realms of possibility that I missed a bit or that a bit flew off into the run while he was working. Apparently lead is sweet and so animals will eat it
A lot of the symptoms fit quite well - the green diarrhoea, weakness, loss of mobility, moping, depression, ruffling feathers, loss of appetite, emaciation. I know they fit most hen illnesses but it's a bit of a coincidence!
I couldn't find electrolytes here and tesco's doesn't have corn syrup (which was in the only recipe I found to make your own) Also gatorade is hard to come by so she's had some powerade which is the only thing I could find at 5pm on a Saturday. She hadn't drunk much all day but she seemed to like the powerade.
She's a lot more alert today and trying to stand a lot. She seems stronger but dehydrated (I pinched some exposed skin and it took ages to relax - I assume that test is the same in hens as it is in humans?!) If it is lead poisoning it must be very mild because she's not showing any of the really bad symptoms like blindness, thank god.
What do you guys think? Ever seen lead poisoning in hens?
