My 4.5 week old Silver Spangled Hamburg just threw up! There was no food in it, it just looked like thick water! There was a lot of it too! She's also been having really loose poo/diarea but I wasn't too concerned until this... Any ideas??? Add: She doesn't seem to be eating much either. Bedding = pine shavings Food = purina chick feed there waterer was cleaned and refilled this morning I have been giving them treats she doesn't seem to go for them. They do get some grit every day as well (with the treats).
