I have a duckling who is two week old and I'm 99% sure is blind/partially blind.... when he/she first hatched he couldn't walk, within a couple of days he/she began walking in circles continuously falling on to her/his back and been unable to get back on his/her feet. He would call for the other duckling when they were quiet as if he thought they had left the enclosure. Even when they were right next to him. I initially thought it was a vitamin deficiency and got him/her extra vit.. since then I have monitored him closely, he/she has stopped walking in circles but still trips over alot onto his/her back. He/she manages to find the food and water but I keep it the same place. He shakes alot if anything changes or I take them for a swim. He/she doesn't swim very well either. I have moved my finger very fast in front of his/her eye and he/she gives no reaction. Iv shown a bright torch and again no reaction. When I put his brothers and sister into the garden enclosure (before moving to the alotment) I tried him out with them n he/she ran around falling over, crying to get out. I have had to keep him/her in a small hutch at home as hes/shes alot smaller than the ones that hatched along side him/her. He/she currently has 3 four day old ducklings for company but I am worried about when these are ready to leave the safety of the indoors, I dont wont him/her to be sad but I dont wont to put him/her with the rest of the flock if its putting her/him in danger. Anyone know what to suggest?
