6 month old tom turkeys got rained on and the weather turned cold 35 degrees. They had shelter but, since we are in Texas they had not seen rain much before. Now their usually pretty blue head with red beards and normal colored snoods are black,grey and one's snood is grey with a red end.............. this happened overnight! They seem depressed and stand on one leg and shake like they are cold even when the temp has gotten back up to 60 degrees. They have not spread their tail feather since. The hen is just fine. ANY suggestions are greatly appreciated. So far no yellow poop although it has been runny.
