Hi
my 2year old hen (hybrid) has recently been falling over. I took her aside for some tlc and her comb is getting pinker, but she tried to run for some treats today and fell on her side, and couldn't seem to get up. What could be wrong. She seemed to be on the mend otherwise..
Hello there and welcome to BYC!
How long has she had a pale comb and been falling over?
Give her an over all exam, starting at the head. Look for any respiratory ailments like runny nose, watery eyes, listen to her breathing for any rattles in the lungs. Look for any bugs she may have....look at the vent area, behind the neck and under the wings. Usually mites leave the skin dirty looking, the bird may be shredding their feathers or even plucking them completely.
Has she been wormed recently? Feel her breast bone. Is she really thin? (you can compare her to the other hen) She could be overloaded with worms.
What exactly does her poop look like? Colors, consistency, etc...
Do an internal exam looking for a stuck egg. (not likely, but always good to rule egg binding out) Put on a disposable latex type glove. Lube up the index finger and gently insert it into her vent straight back. If she has a stuck egg, you will feel it within the first 1 to 2 inches.
Check her legs and bottoms of her pads for any bumblefoot or injuries.
Feel between her legs and back toward the vent, on the outside of her body. Her abdomen shouldn't be bloated or squishy. (feel the other hen for comparison.)
Could she have gotten into anything toxic?
Mareks Disease might need to be considered if it is none of the above. The bird will get weaker and weaker, continuing to stumble, using their wings to stabilize themselves as they hobble around.
See what you can find or think of after going over all these things I listed above.
Keep us posted!
