I have tick very bad and guinea are not the answer at this time. I do plan on getting some guinea eggs and hatching them so that I can raise them myself. The ticks are so bad that when you walk around outside you spend more time picking tick off then getting to where you want to go. I need to know something that I can use right now that is safe after a day or so for my chickens to go back out. I only have three that are free ranges where the ticks are. I can pen them up for some time so something can work but again what can I use. I was thinking of using Sevin granules. AGAIN GUINEAS ARE NOT THE ANSWER AT THIS TIME. Thank you.
