Need some advice! I have 3 10 week old. Chicks with own 1 year old olive egger. I saw some small amounts of blood is some droppings today. I am thinking from the older hen and one of the younger ones. Very small amount. The younger one is sneezing as well. No blood noted on their bottoms. I did not see worms but I did treat with the smart guard de wormer for the big girl as a precaution. I have 1tsp of corrid in their 1 gallon water dispenser. Anything else I should be doing? Also to add the 1 year old hen has not laid an egg in a week but is pooping. Feeling all flock and she doesn’t seem to want the oyster shell. I give her crushed egg shells as well.
