I lost three chicks without on different days and no signs of anything being wrong with them. Today I go out to let then out of the coop and the last chick is dead and my hen has foamy white stuff coming from her eyes. Her face doesn't llok right like its we or the feathers are missing a bit. What is wrong with her?? Can I give her anything??? I ran out of food so she has been eating the starter grow feed and last night the feed store was closed so I gave her bread.
