I made another post about 6 weeks ago for one of my pullets going from wobbly/unsteady to toppling over, not being able to stand, not wanting to eat/drink, etc to unfortunately passing away. Now the 2nd pullet that I got with her is unstable/wobbly on her feet starting two days ago. (I got 2 pullets and a cockerel at a tradeshow- the cockerel is having the cocci type poop) I bought these 3 mid June. They are still separated from my other flock of 6 (who are very healthy and laying). The only difference since I've had them is I've moved them into this new coop (a converted new shed bought from Home Depot) with the pen on gravel and 1/3 garden dirt. They get out to free range too (the prev pullet didn't as she got sick). Idk what to do. Or what it is. I don't know if it's mareks? Worms? Etc. I was able to get piperazine dihydrochloride 53 today from feed store. They have vitamins in water, I've been doing occasional acv, de.
