[yeziroo93]

2 weeks ago i bought a hen then a rooster and im so lost theyre both 1 year old the hen sleeps on top of the nesting box in the day and perches at night the rooster on the other hand is a different story just 3 days ago his legs started looking red like sunburnt he poops sloppy from time to.time but usually its regular poop he sleeping standing up in the day and i cant get him to roost which wasnt a problem before also theyve been moved from make shift coop to makeshift coop until i recently got a chicken coop from my uncle... should i seperate the rooster because the hen seems to be fine

Post picture of the leg here and many will offer help and review the https://www.backyardchickens.com/f/10/emergencies-diseases-injuries-and-cures section. As far as separating them now, if he was contagious she would also have it but sounds from your description like a leg infection that progressed into a bit worse, time to get on some medication.
