Hey guys, i have one of my goats that is naturally smaller than the others and i have de wormed him twice and treated his foot rot. He is walking fine and shows no sign of worms. He always lays down and has droopy eyes and walks slower than the rest. I have saw him nibble on hay,grass a coupe timesand drink but he never eats corn or grain. I put him in a seperate pen with a couple cows and 1 other goat....help! What should i do?
