i have a few 4 month old chickens (araucana crosses) i was pretty sure from early on that is was 3 hens, 2 roos, which was confirmed on here. anyhow the 3 hens are doing fab, so is one roo, but the other roo always looks sick, especially after just getting over cocci too. he's always pale (comb and wattles) hangs at the back of the crowd, doesnt crow and just seems to slowly be getting worse (we thought we'd lost him the other week he was rolling round the floor couldnt walk not eating, pooping yellow runs etc etc but after treatment for cocci he got back to his usually quiet, sick looking self. anyhow i noticed yesterday how small he is compared to his brother, and how thin his legs are! (they are even thinner than the hens legs!) so im wondering, as he's not been good since hatching, could it be a long drawn out failure to thrive case...Or simply a way down low in the pecking order roo?
